Calculation of inviscid three-dimensional supersonic flows with heat and mass addition

The method follows previous work in that the streamlines are constructed simultaneously with the solution of the gas-dynamic equations written in streamwise coordinates. The flow envisaged is three dimensional, which implies that two unknown parameters need to be chosen in order to guide each free streamline over an incremental distance. In general this leads to two errors in cross-plane pressure gradients which are reduced to zero by Newton's method, and the calculation then proceeds to the next downstream step and so on until the required flow field is complete. Heat and/or mass addition is allowed if required and the ratio of specific heats is permitted to vary with temperature.
