Numerical simulation of external and internal gasdynamic problems

The application of numerical techniques for the solution of various external and internal inviscid gaseous flowfields is considered. The construction of numerical codes is discussed. This discussion includes the comparison of explicit and implicit finite-difference schemes, the examination of possibilities of the shock-capturing techniques and the consideration of nonregular nets. Also the order of the finite-difference approximation is analysed. The effectiveness of these principles is demonstrated for various flowfield simulations.
