Shock Ways
Hi, I want to know about shock ways why its generates and why its generates only in supersonic flows. bye

Re: Shock Ways
Solution of flow problems based on invicid theory breakdown at certain level. The discontinuties called Shock waves are accepted as jump discontinuties to save the solution. This happens when the true physics i.e., viscosity & thermal conductivity are ignored in modeling the fluid.

My question is that why this discontineuties generate

Re: Shock Ways
The reason shock waves are generated is simply that in a hyperbolic system information is propagated along the so-called characteristic directions and when two members of the same characteristic family intersect the solution becomes multivalued; i.e. for the same instant in time and position in space there are two different values for the density,velocity, etc. In physical space the multivaluedness is removed by replacing it with a surface of discontinuity - the shock wave.
See the books Linear and nonlinear waves by G.B. Whitham High speed flow by C. J. Chapman Supersonic flow and shock waves by Courant and Friedrichs Tom. |
