摘　　要：本文在计算任意形状流道中二维粘性不可压缩定常流动的流线迭代法的基础上,进一步提出一种隐式流线迭代法。本文首先导出粘性不可压缩流动的新的总压方程,然后采用隐式方法对该总压方程进行数值计算。算例计算表明了本文所提出的这种隐式流线迭代法能提高收敛速度和减少计算时间。This paper presents the implicit method of streamline iteration on the bases of method of streamline iteration for computing two-dimensional viscous incompressible steady flow in the channel with arbitrary shape. Firstly, a new total pressure equation of the viscous incompressible flow is introduced in this paper. Then, this equation is numerically computed by use of the implicit method. It is shown from the computational results of the examples that the implicit method of streamline iteration can speed up the convergence and decrease the computational time.
