特性曲線法による二次元平面流れの数値解析法に関する2,3の検討

Abstract

This study deals with an application of the characteristics theory to numerical simulationtechnique of two-dimensional plane flows. Two cases with and without non-linear term inbasic equations are considered. Transformations of these equations of each case into thecharacteristics forms are described in detail. The difference equations and interpolationmethods deduced are discussed. The results of numerical simulation of the flows in southernpart of Lake Biwa show that the schemes developed here may include a numerical viscosityin both cases of linear and parabolic interpolation.
