| 摘 要： | 通过进行前体的边界层效应修正、采用有限化学反应速率模型和中心差分形式的Mac Cormack格式,求解燃烧室性能分析模型方程,以及采用灵活的发动机性能计算方法等,建立了较为完善的RBCC发动机性能分析模型及软件,并进行了软件应用研究。分别采用二维CFD计算和试验结果对该模型进行了校验,其相对误差小于10%。结果表明,该软件适用于RBCC发动机性能分析。

| Abstract: | Based on boundary layer effect correction technique for fore-body,the model equation for chamber performance analysis was solved by using finite reaction rate model and MacCormack scheme with central difference form.A more perfect model for RBCC motor performance analysis was established by means of flexible motor property calculation method,and application of the software was investigated.The model was checked by using 2D CFD calculation and test results,and the relative error is less than 10%.The results show that the software is applicable to RBCC motor performance analysis. |
