摘要

PROBLEM TO BE SOLVED: To find out a flow rate and pressure in a three-dimensional(3D) flow on the same grating point and to easily calculate the movement of a free surface by executing repeat calculation for finding out the flow rate and pressure by using respectively specified momentum expression, pressure expression and speed correction expression and finding out the flow rate and pressure on the same node. ;SOLUTION: A momentum expression discretized on the basis of a control volume method, a pressure expression obtained by discretizing a pressure term after substituting a momentum expression half discretized by removing a pressure term for a discretized continuous expression and a speed correction expression derived from the discretized momentum expression are used. Thus repeat calculation for finding out a flow rate and pressure is executed to find out the flow rate and pressure on the same node. Calculation can be stably executed by using the pressure expression in which a solution derived from the momentum expression and the continuous expression by executing discretization based on the control volume method does not generate spatial vibration and accurate calculation can be executed even in the case of using comparatively rough element division.;COPYRIGHT: (C)1999,JPO
