摘要
综述了3种不同维数的喷射器射流场流动模型的研究工作,分析了3种模型各自的特点后指出,一维模型的建立主要基于定压混合理论或定常面积混合理论;二维偏微分方程模型建立后基于差分法等数值算法进行求解。随着网格技术和计算方法的提高,三维粘性射流场中激波和湍流的数值模拟发展迅速。
The research work on the models of the flow in steam ejector is reviewed and summarized with 48 references. The characteristics of the models are analyzed：l-D model is based on the theory that the mixing process is completed in a constant area or under a constant pressure. 2-D P. D. E model is solved by FDM. As the grid computing and calculate technology developed, the researches of simulations on the shock waves and turbulence in the 3-D viscous flow are becoming hotter.
