Abstract
Turbulence modelling plays an important role in the numerical prediction of nonequilibrium condensations in transonic flows. The present study evaluates the effect of four different turbulence models, namely, k - ε standard, RNG, realizable, and k - ω SST, on the condensation behaviour in transonic flows considering shock waves. The numerical simulation is compared to experimental data, which demonstrates that the k - ω SST model shows better performance than k - ω turbulence models in predicting the nonequilibrium condensation and shock waves in transonic flows.
