用时间相关法的显格式求解氢氧发动机喷管的粘性化学反应流动，采用６种组分，８个基元反应有限速率的化学反应模型，湍流模型采用Ｂａｌｄｗｉｎ－Ｌｏｍａｘ代数湍流模型，得到流动参数和产物的质量分数在喷管流场中的分布。计算结果表明，采用显格式方法求解喷管化学反应粘性流动是可行的。
The time-dependent method was used to solve the viscous chemical reaction flow in the oxyhydrogen injection nozzle. The chemical reaction model with six components and eight basic reaction limited rates was used. The turbulence model was based on the Baldwin-Lomax algebraic turbulence model. The flow parameters And the product mass fraction in the nozzle flow field distribution. The calculation results show that it is feasible to use the explicit method to solve the viscous flow of chemical reaction nozzle.
