What Oblique Shock Calculator does

An oblique shock calculator that determines the flow properties of a gas passing through an oblique shock wave. Users input the upstream Mach number, wave angle, and specific heat ratio to receive outputs including downstream Mach number, pressure ratio, density ratio, temperature ratio, and the normal component of velocity. The tool is designed for analyzing gas compression in scenarios such as aircraft intake design, where shock waves must be managed to subsonic speeds before engine combustion.
