The equations of compressible flow The equations solved are the 3D unsteady Euler equations, governing inviscid compressible flow, where the summation convention on repeated indices has been applied, is the density, is the velocity vector, is the specific total energy, is the specific internal energy, and is the pressure. , , and are source terms that arise from the application of the method of manufactured solutions, used for verification; these source terms are zero when computing practical engineering...
