Physical criterion study on forward stagnation point heat flux CFD computations at hypersonic speeds

In order to evaluate uncertainties in computational fluid dynamics （CFD） computations of the stagnation point heat flux, a physical criterion is developed. Based on a quasi-one-dimensional hypothesis along the stagnation line, a new stagnation flow model is applied to obtain the governing equations of the flow near the stagnation point at hypersonic speeds. From the above equations, the compatibility relations are given at the stagnation point and along the stagnation line, which consist of the physical criterion for checking the accuracy in the stagnation point heat flux computations. The verification of the criterion is made with various numerical results.

General Solutions of Thermoelastic Plane Problems of Two-Dimensional Quasicrystals

The thermoelastic plane problems of two-dimensional decagonal quasicrystals(QCs)are systematically investigated.By introducing a displacement function,the problem of thermoelastic plane problems can be simplified to an eighth-order partial differential governing equation,and then general solutions are presented through an operator method.By virtue of the Almansi′s theorem,the general solutions are further established,and all expressions for the phonon,phason and thermal fields are described in terms of the potential functions.As an application of the general solution,for a steady point heat source in a semi-infinite quasicrystal plane,the closed form solutions are presented by four newly induced harmonic functions.

Volcanism and Earthquakes<br/>—Polemical Notes on Mantle Plumes

The article presents new views on volcanism and earthquakes. The problem of the scientific basis for the interpretation of geotectonic theories was discussed. The interpretation of the mantle plume phenomenon according to the theory of expansion and the theory of primal forces of nature is presented. The heat source in the Earth’s core is thermonuclear reactions. The cause of earthquakes is not collisions of lithospheric plates, but plasma eruptions. The stresses in the rock mass, causing global fractures, arise due to the increase in the size of nuclides in the process of plasma recombination. The oldest basalts that make up the oceanic plates remain invariably along the shores of continents. The widespread view of the subduction of lithospheric plates and vertical convection cells of rock matter should be regarded as a scientific fiction.

Key Points and Solutions to Enhance the Curative Effects of Moxibustion Therapy

Objective： To elucidate the key effects of moxibustion points and quantity of moxibustion used in order to enhance the curative effect of moxibustion therapy. Methods： It analyzed the occurrence rules of acupoint heat-sensitization and its relationship to the moxibustion location and dose, in view of the original definition of acupoints in Nei Jing （Internal Canon） and the acupoint heat-sensitization in clinical practice. Results： （1） The original definition of acupoint is the reflecting area of a disease on surface of the body, which is individualized, motive and sensitive; （2） The location in which heat-sensitization is generated relating to a heat-sensitive acupoint, which therefore depicts the best choice for point selection and also the most accurate area to give moxibustion; （3） The heat-sensitization time can be taken as a clinical index to quantify the moxibustion dose, in order to apply sufficient moxibustion for each individual. Conclusion： The key points for enhancing the curative effect of moxibustion therapy are to identify heat-sensitive points and a scientific moxibustion dose.
