摘要：In this paper two pseudostream functions are defined in view of the characteristic featuresof the momentum equations and the requirement of continuity. The principal equationsof eiher pseudostream functions only contain the terms of its own second-order partial deriv-atives and do not include those of the other, and these equations can be easily solved. Theentire three-dimensional solution is then obtained through solving the principal equations ofboth pseudostream functions separately and iterating the two solutions. The
