In order to accurately predicting the flow field inside the cavity structure of the supersonic combustor, cold numerical simulation of the flow field of the cavity was studied. Use the Fluent software and SST k-ωturbulence model, six kinds of vertical height ratio of the flow characteristics of the situation cavity was analyzed. The research result has a certain reference for providing a better understanding of the cavity flow field, optimizing the configuration of the cavity and designing of high efficiency flame holder.
