Abstract—In this study, k-ε model has been used to examine supersonic ﬂow in a model scramjet combustor. The conﬁguration used is similar to the DLR (German Aerospace Center) scramjet model and it is consists of a one-sided divergent channel with a wedge-shaped ﬂameholder at the base of which hydrogen is injected. Here, we investigate supersonic cold ﬂow with hydrogen injection. For the purpose of validation, the k-ε results are compared with experimental data for temperature at the bottom wall. In addition, qualitative comparisons are also made between predicted and measured shadowgraph images. The k-ε computations are capable of predicting cold flow simulations well and good.
