Abstract: | Summary The effect of the Prandtl number on the variation of entropy across shock waves is calculated, using the Navier-Stokes equations for the gas phase. The resulting system of three ordinary nonlinear differential equations is reduced to a system of two autonomous nonlinear differential equations, which are solved exactly. This solution, is obtained formally by assuming that the Prandtl number is equal to 3/4. A comparison of the behavior of entropy across shock waves for different values of Prandtl number is given. |
