Abstract

A newly developed numerical solver for supersonic flow is validated using a non-reacting, hot gas channel flow. The solver is embedded into the open-source software package Open- FOAM, thus allowing massive code parallelization. It uses a transient approach and includes the support of multi-species transport and chemical reactions. A local time stepping technique is applied to remedy the effects of the acoustic Courant number restriction and to speed up convergence. The evaluation is conducted using both experimental data and numerical results of a commercial CFD code. Different flow Mach numbers and wall resolution techniques are evaluated and compared. Two- and three-dimensional simulations with the new solver are shown to provide quasi-steady-state solutions which are comparable to those of the commercial code. In addition to the investigation of the hot gas channel flow Schlieren images obtained for cold flow conditions are compared to the numerically predicted flow field and good agreement is demonstrated. The presented work provides a supersonic channel flow test case, which establishes the basis for further enhancement of our newly created solver.
