The Study of Visualization and Modeling of Full Potential Equation with the Influence of Small Disturbance Based on Python

Abstract

This paper design a program based on the full potential equation aiming to visualize the fluid field around the disturbances and see how the disturbances influence the fluid flow. In the process, this article use central difference scheme for subsonic cases, while for supersonic cases, upwind scheme is applied to rewrite the equation to get the exact models. And also calculate the error to show that the models work well. The error graph shows that the results of the modeling. Fit the full potential equation theory which means the method is feasible.
