摘要
对燃气排导箱内的典型三维稳态流动过程进行了粘性不可压数值计算，采用较为成熟的ＳＩＭＰＬＥ方法。所发展的计算程序可求解质量、动量和能量守恒方程，ｋ－ε双方程湍流模型方程，以及热辐射通量方程，并进行了程序的算例验证。三维燃气排导箱内的计算结果也得到了一些实验测量的数据的验证，得出一些有工程实用价值的结果和结论。
By the use of the SIMPLE method,some numerical computations on a typically 3-Dsteady state incompressible viscous flow in the gas exhaust chest are made,The program developed can be used to solve the mass conservation equation,the momentum equations,the energy conservation equation,the k-ε turbulence equations and the heat radiation flux equations,and it is examined by some computational models. The computed results of the gas ex-haust chest are compared with some test data,and some useful results and conclusions for engineering design are obtained.
