Prandtl Meyer Expansion Calculator

Calculates the physical properties of fluid flow downstream of an expansion wave, utilizing the principles derived from Prandtl–Meyer theory. Users input initial conditions, such as the upstream Mach number or angle of deflection, allowing the tool to determine resulting values for local speed, pressure, and the angle of the flow relative to the incoming direction. The calculation models how a supersonic stream expands through a corner or discontinuity, providing necessary data points required for aerodynamic analysis in compressible flow regimes. Engineers and advanced physics students use this calculator to analyze complex fluid dynamics scenarios where shock waves are not present. It is particularly useful for validating theoretical derivations regarding flow turning and expansion geometry.
