The results stemming from the calculation of heat transfer in torch furnaces by the laws, relating to radiation from solid surfaces and gas volumes are analyzed. The article presents the laws for radiation from gas volumes and the procedure for calculating heat transfer in torch furnaces, fire boxes, and combustion chambers, elaborated on their basis. The example of heat transfer calculation in a torch furnace is given, and it is significantly non-uniform in nature. Non-uniformity of heat flux distribution on heating surfaces is given. According to the results of calculations, a new furnace is designed to decrease the non-uniformity of ingot heating, fuel rate, and increase the furnace capacity. The calculation results of the distribution of heat fluxes on the heating surfaces are given in changing torch geometric dimensions. These results are confirmed by experimental studies. 展开更多

The influence of the transfer payments from the central government to the local governments on the local governments' efforts on taxation must be taken into consideration by every country for the design of the transfer payments. Based on the theoretical analysis on the influence of the transfer payments from the central government to the local governments' on the local governments' payments', this paper indicates that the local governments' efforts on taxation depends on the demand elasticity of the district for public goods, It increases with the increase of the elasticity. Judge the degree of the local govet:nment's efforts on taxation by measure 2. After an empirical analysis on the transJer payments from the central government to the local governments'from 2000 to 2004, this paper gets the con- clusion that the local governments' effbrts on taxation ctbates with the increase of supporting payments or with the increase of the ratio of transfer payments to local wiliing public paymentS. Under speCific Circumstances, the higher the ratio of transfer payments to the local fiscal expenditure is. the smaller the local governments' efforts' on taxation is" under the central payments, whereas' the higher the local income is, the higher the efforts is under the central pav- ments. Based on this', this paper gives the meaning of its eOrresponding pofiCieS. " 展开更多

Based on the entropy generation concept of thermodynamics, this paper estabfished a general theoretical model for the analysis of entropy generation to optimize fins, in which the minimum entropy generation was selected as the object to be studied. The irreversibility due to heat transfer and friction was taken into account so that the minimum entropy generation number has been analyzed with respect to second law of thermodynamics in the forced cross-flow. The optimum dimensions of cylinder pins were discussed. It's found that the minimum entropy generation number depends on parameters related to the fluid and fin physical parameters. Varlatioms of the minimum entropy generation number with different parameters were analyzed. 展开更多

Thermal conductivity is assumed to vary as a linear function of temperature. The transformed governing equations in the present study are solved numerically using the Runge-Kutta method. Through a comparison, results for a special case of the problem show excellent agreement with those in a previous work. Two cases are considered, one corresponding to a cooled surface temperature and the other to a uniform surface temperature. Numerical results show that the thermal conductivity variation parameter, the injection parameter, and the power-law index have significant influences on the temperature profiles and the Nusselt number. 展开更多

A hill can be regarded as an environmental carrier of heat.Water,rocks and the internal moisture naturally pre-sent in such environment constitute a natural heat accumulator.In the present study,the heat and moisture trans-fer characteristics in a representative hill cave have been simulated via a method relying on the Darcy’s law.The simulations have been conducted for both steady and unsteady conditions to discern the influence of permeability and geometric parameters on the thermal and moisture transfer processes.The reliability of the simulation has been verified through comparison of the numerical results with the annual observation data.As revealed by the numericalfindings,the internal temperature of the hill accumulator is proportional to the permeability,outside surface temperature,overground height,underground constant temperature layer depth,and underground tem-perature of the hill,and it is inversely proportional to the horizontal size of the hill.Moreover,in the considered case,the order of magnitude of the permeability of the hill is contained in the range 10-15–10-13,and displays a certain sensitivity to the rainwater seepage. 展开更多

Nowadays some new ideas of fractional derivatives have been used successfully in the present research community to study different types of mathematical models.Amongst them,the significant models of fluids and heat or mass transfer are on priority.Most recently a new idea of fractal-fractional derivative is introduced;however,it is not used for heat transfer in channel flow.In this article,we have studied this new idea of fractal fractional operators with power-law kernel for heat transfer in a fluid flow problem.More exactly,we have considered the free convection heat transfer for a Newtonian fluid.The flow is bounded between two parallel static plates.One of the plates is heated constantly.The proposed problem is modeled with a fractal fractional derivative operator with a power-law kernel and solved via the Laplace transform method to find out the exact solution.The results are graphically analyzed via MathCad-15 software to study the behavior of fractal parameters and fractional parameter.For the influence of temperature and velocity profile,it is observed that the fractional parameter raised the velocity and temperature as compared to the fractal operator.Therefore,a combined approach of fractal fractional explains the memory of the function better than fractional only. 展开更多

Wet compression is an effective way to enhance the performance of gas turbines and it has attracted a good deal of attention in recent years. The one sidedness and inaccuracy of previous studies,which took concentration gradient as mass transfer potential are discussed. The mass transfer process is analyzed from the viewpoint of non equilibrium thermodynamics,by taking generalized thermodynamic driving force as mass transfer potential,and the corresponding mass transfer coefficient is obtained using the heat and mass transfer equilibrium occurring between moist air and water droplets at wet bulb temperature for the sake of avoiding complex tests and providing more accurate formulas. A mathematical model of wet compression is therefore established,and the general laws of wet compression are investigated. The results show that the performance of atomizer is critical for wet compression and wet compression is more suitable for compressors with higher pressure ratio and longer compression time. 展开更多

By a survey of a range of existing literatures, this article makes a rough summary for previous theoretical findings about the role of side payment in international environmental agreements. If countries are symmetric, we can hardly exploit the transfer to enhance international cooperation. On the contrary, under asymmetric countries assumption, the side payment is often helpful to obtaining better global outcome in environmental issues. Even though no general theoretical conclusion can be claimed so far, many meaningful implications will be revealed with the going on of this article. 展开更多

An experimental study and theoretical analysis were carried out to explore the ground-borne vibration generated by elevated high-speed railway in rock strata.Taking a typical rail line constructed on rock area in China as the research object,a set of field tests was performed on Rizhao-Lankao High-Speed Railway,the bridge and ground vibrations were measured as trains passed at 330−340 km/h,then the transferring law and spatial distribution under individual frequencies were investigated.The experiment results indicate that the bridge frequency spectrum exhibited relatively high-frequency vibration peaks caused by short-wavelength irregularity;ground vibration farther than 30 m away can be amplified with a higher frequency and numerous components.Furthermore,the wave propagation equation of a stratified rock strata was established based on direct-stiffness method to explore the vibration attenuation rules via frequency-domain analysis.It is found that the rock area has a weaker correlation between vibration transmissibility and frequency,thicker and harder rock strata loss their vibration attenuation capacity.It can be concluded that the high-speed railways induced vibration on rock strata shows a wide frequency band and large amplitude,the design of reducing vibration aimed at specific frequency is important according to next more detailed numerical study. 展开更多

In this paper, a two-region endogenous growth model is adapted to analyse Western China's development,and regional divergence and convergence processes. Dynamic optimization is utilized to calculate the growth rate of the Chinese economy on the optimal growth path, and backward integration is utilized to simulate the evolvement of some key indicators, including relative GDP per capita of Western China to Eastern China, regional capital growth rate and regional GDP growth rate. The calibrations of this model after 1992 are conducted. The calibration results provide evidence about the speed of Western China's relative development, and also shed some light on the future regional convergence process under the Western Development Programme launched in 2000. 展开更多

The competitive attitude of the member states of the EU (European Union), to become the most attractive for companies results in law reforms aiming at more flexible conflict between shareholders. Besides, the economic objective of avoiding a company's dissolution, the English, Dutch, and Belgian exit proceedings for the settlement of disputes between shareholders set up a social objective: protecting the interests of the minority shareholder of a private limited company. The paper consists of four chapters. The introduction lays out the necessity of buy-outs for shareholders of a private limited company. The first chapter describes the different facts justifying the buy-out of a shareholder on the basis of serious grounds. The second chapter presents the findings of a comparative research of the valuation of the shares transferred in an English, Dutch, and Belgian procedure. Finally, the conclusion summarises in which way the English, Dutch, and Belgian legal system protect the interests of the minority shareholder of a private limited company. 展开更多
