摘要
本文提出气相多组分方程组采用时间推进法，把混合气连续方程同状态方程相联系，把密度的调整量转化为压力的调整量，计算绝对压力场，对大温差下的有化学反应的多组分炉内流场进行计算，获得成功．
It is presented New numerical method in which is employed time approach method formulti--species diffusion equation and transformed the density adjustment into pressure adjustment by linking up the status equation and continuity equation together for calculatingabsolute pressure field. Using this method we have successfully c3lculated flow fields in uniform temperature and large differential temperature, and even flow field containing reactiono f multi-species. It is different numerical method than commonly SIMPLE series methods.
