Summary
For the design of air-breathing hypersonic vehicles the simulation of the flow inside the propulsion system is of essential interest. In order to allow accurate computation of the expanding flow of a hydrogen/air mixture at high temperatures, the chemical and vibrational nonequilibrium effects must be taken into account. In the present study the influence of thermal nonequilibrium on flows in SERN-type nozzles is numerically investigated. In the Finite Element code used for the flow simulation chemical reactions are modeled by finite rate chemistry and vibrational relaxations are modeled by the Landau-Teller theory. As test case a basic nozzle experiment is computed and the results are compared with measured data. In order to estimate the thermal nonequilibrium effects in true scaled nozzles the DLR/ONERA’s JAPHAR nozzle flow is computed.
