Abstract
The dual-mode scramjet combustor is a promising candidate for the combined cycle engine of the hypersonic airplane, and the flame propagation and stabilization process in the dual-mode scramjet combustor has a great impact on its performance improvement. In this survey, the research progress on the flame propagation and stabilization in the dual-mode scramjet combustor is reviewed and summarized, and its main focus is on the flame stabilization mode, especially for the mode transition. The flame stabilization process in the dual-mode scramjet combustor is summarized from three aspects, namely the combustion mode classification, the mode transition and the vitiation effect. The obtained results show that the operational conditions and the geometric parameters both have a great impact on the flame propagation and stabilization process in the dual-mode scramjet combustor, and there exist strong interactions between the geometric parameters, as well as the operational conditions. This is a multiobjective design optimization problem, and the optimal operational conditions, as well as the optimal geometric parameters, should be obtained by the optimization algorithm based on the surrogate model with high fidelity.
