Boundary conditions in a TVD scheme for Euler equation in a finite element formulation
Abstract
An arbitrary mesh generated by means of triangular and quadrilateral elements is presently used to model twodimensional CFD Euler equations. Five distinct types of boundary condition are treated: total reflection, supersonic inlet or outlet, and subsonic inlet or outlet. In the first of the illustrative calculations presented, both of the jets modeled at 45 deg to each other are supersonic; in the second calculation, the 45deg jet is brought to subsonic conditions in which the stagnation pressure is reduced by a factor of 10.
