摘要将时空守恒元-解元（CE/SE）方法推广到二维粘性流动问题。的制定和讨论。将扩展的CE/SE方法应用于二维粘性流动问题，如边界层流动、通道入口流动、后台阶流动和空腔流动。给出了数值计算结果，并与解析结果和实验数据进行了比较.结果表明，该方法能够较好地预测粘性流动和传热特性。还证明了该方法既能求解高速流动，又能求解低马赫数流动。
Abstract The space–time conservation element–solution element (CE/SE) method is extended to two-dimensional viscous flow problems. The formulation is presented and discussed. The extended CE/SE method is applied to several 2D viscous flow problems, such as boundary layer flow, entrance of channel flow, backward facing step flow and cavity flow. The numerical results and their comparison with analytical result and experimental data are presented. The capability of this method for predicting viscous flow feature and heat transfer is demonstrated. Also the capability of the method to solve both high-speed flows and low-Mach number flows is demonstrated.
