Derivation of a Godunov One Dimensional Fluid Dynamics Code
Abstract
This reports details the development of a one dimensional code using the Godunov method, which is the first part of a larger effort to develop an axisymmetric fluid dynamics code. The ultimate objective flow field associated with a shaped charge jet, in order to study how and to what extent perturbations of the jet are caused by interactions of the flow field with various target geometries. The report contains detailed derivations of the equations involved in the one dimensionals Godunov method, and the incorporation of these equations into a computer program. Many of these basic relationships are applicable to the axisymmetric code. A shock tube experiment was conducted to test the predictions of the program. The program accurately predicted all aspects of the shock tube flow, being within 2% of experimental values for pressure, 6% of experimental values for velocity, and 1% of theoretical values for density.
