高温状态下温度场的计算

The Temperature Field Calculation of the High-Temperature Thermal State

本文将湍流流场计算的ＳＩＭＰＬＥ算法与辐射传热的热流法计算结合在一起，联立求解了高温状态下炉内的流动及温度分布情况，得到了气体流动的速度场以及由传导、对流和辐射共同作用的温度场分布情况。通过计算比较，从定量的角度验证了高温状态下辐射传热的主导作用。

This paper compares the calculation of radiative heat transfer model with the K-ε two equations turbulence model of 2-D fluid flow calculation.A computer program which contains two models has been developed, that uses the SIMPLE algorithm of fluid flow calculation and the heat flux method. The thermal state of high-temperature can be researched, which involves the velocity and temperature fields acting on conduction, convection and radiation of heat transfer.Through the calculation,the radiative heat transfer proves to be the major section in the high-temperature thermal state.
