A method for the standardized calculation of gas flows in a region with an arbitrary boundary
Abstract
A unified approach is proposed for the finitedifference calculation of two and threedimensional nonstationary gas flows on a Cartesian or cylindrical rectangular stationary Euler grid in a region of arbitrary complex form that may vary with time. Stationary solutions are obtained by using a finitedifference scheme in time; calculations for the boundary and internal cells are carried out using unified difference formulas. Since mostly coarse grids are used, it is essential that the difference scheme be conservative. The conservativeness of both the difference scheme and the boundary conditions is ensured by using the integrointerpolation method.
