Key Features of Numerical Simulation of Supersonic Gas Flows around Blunt Bodies by the Meshless Method
摘要
Abstract
A meshless method for solving the Euler system of equations for the inviscid gas flow in a three-dimensional space is described in detail. Polynomial Least Squares approximation of partial spatial derivatives of gas-dynamic parameters and the transformation of an orthonormal coordinate system are used for calculating the fluxes between the computational nodes.
