Abstract
A new kind of explicit-implicit differential scheme is developed in this paper. The process of the boundary information propagation is accelerated with the immediate- update method in which the information of the n+1 time step is applied. Meanwhile, the form of the implicit part is simplified and the matrix calculation is avoided. An example on a quasi-one dimensional flow in a Laval Nozzle is provided, which testifies the efficiency of the new scheme with the result of saving about three quarter to half of the calculation time compared with the old scheme.
