Effects of mass diffusion coefficient and heat loss on walls on flame shape are investigated.
研究了质量扩散和壁面散热对火焰形状形成的影响。
The influence of mass diffusion coefficient on the coupled heat transfer is small, and the increase of Reynolds number can restrain the component diffusion.
质扩散系数对耦合换热的影响很小，入口雷诺数的增加会抑制质扩散。
The results calculated by algebraic model in GASFLOW are different from the other results in the simulation of mass diffusion, momentum diffusion, and parameters fluctuation.
而GASFLOW中代数模型未能较好地模拟氢气的质量扩散和动量扩散，氢气的浓度场分布与其他模型的计算结果存在较大的差别。
