Becker–Morduchow–Libby solution
The Becker–Morduchow–Libby solution is a mathematical description of how the properties of a gas—such as pressure, temperature, and density—change within a one-dimensional shock wave. It is an exact solution of the Navier–Stokes equations for a compressible, viscous, heat-conducting gas.
