Abstract
In order to calculate the vibrational non-equilibrium flows in gasdynamic laser nozzles, a six temperature kinetic model is implemented in the open source CFD toolbox OpenFOAM. A new solver using central-upwind scheme is developed to solve the 2-dimensional coupled equations. To validate the new solver, numerical analysis of small signal gain coefficient in two minimum-length contoured nozzles at corresponding condition is carried out. The results obtained are in satisfactory agreement with the published experimental data, showing the validation of the solver. Profiting from the excellent parallel performance of OpenFOAM, numerical results could be quickly obtained to predict and refine the performance of the gasdynamic laser devices.
