Abstract
When one-dimensional supersonic compressible flow undergoes a sudden retardation, a normal shock wave may occur. After the shock wave, the fluid properties can be obtained if continuity, momentum and energy balance laws are used. The method to compute the thermal and caloric properties of the fluid is explained in brief. A suitable FORTRAN 77 computer code is proposed, developed, tested and run with the operating system VMS on a MicroVAX II. With minor changes, it can run with MS-DOS on a PC/XT. The refrigerant R22 has been used as a fluid. Its thermal and caloric equation of state and the corresponding values are given in the following subroutines. Some results are given to check the code by potential users.
