[S02C-01] Fundamental Study on Computational Method of 2-D Convective Equation by Means of Spatial Moment Method
Keywords:Convective Equation, Spatial Moment Method, Numerical Oscillation
This paper describes a computational method for a 2-D convective equation using the spatial moment method with a 2-D linear shape function. A 2-D spatial moment method is applied to reproduce a few types of discontinuous distributions such as a cube with the procedures to suppress the numerical oscillation. The computational method is also applied to the 2-D convective equation after integrating 2-D convective equation over 2-D space. It was pointed out that applying the spatial moment method with TV2 method, the convective process of a discontinuous function could be reproduced reasonably.
