Some anomalies of numerical simulation of shock waves. Part I: inviscid flows

摘要

In this part, nonunique solutions of potential and Euler equations are discussed. Previous work related to the airfoil problem is reviewed and some new results are presented. Simple models based on Burger's equation and quasi-one-dimensionalnozzle flow are examined. An example for a three-dimensional wing admitting nonunique solutions of the potential and Euler equations is also included.
