One dimensional propagation of shock waves through clouds
Abstract
The finite difference methods of Lax-Wendroff (two step) and MacCormack are used to solve the flow of a plane shock wave entering and propagation through a semi-infinite two phase mixture consisting of an inert gas, water vapor, and water droplets. Finite difference methods were studied for an air-air shock tube. It is concluded that the antidiffusion method of Boris and Book (1973, 74) is a powerful corrective procedure to the more basic methods. The results for the near field transmitted wave obtained by the finite difference approach are in good agreement with results by Kao (1983) using the method of characteristics. The advantage of the finite difference method is its adaptability to two and three dimensional problems.
