The area of a shockwave is the most specific area of a supersonic gas flow because its general shape is affected not only by the gas itself but also by the pressure difference between the operating (input) pressure and the atmospheric (output) pressure and by the shape of the aperture or jet the gas passes through. Simulating a supersonic gas flow leaving a jet into a high-pressure area requires to use specific constant values depending on the type of the gas and boundary conditions, which were already experimentally verified. However, when simulating a supersonic gas flow entering a low-pressure (or vacuum) area, different constant values are needed. This paper deals with a possibility of using optical methods for displaying a shockwave within a low-pressure area in order to modify a numerical model of the flow to make the simulated shockwave match the one from experiment.
