Direct Numerical Simulations of flow phenomena related to Rotating Detonation Engine combustion chamber

Rotating Detonation Engine gains increased interest due to numerous advantages of detonation combustion mode in comparison to deflagration. It is also superior to Pulse Detonation Engine (PDE) by means of continuous work, stable thrust output, simpler design and ability to easily apply of aerospike nozzle. It is expected, that efficiency of Rotating Detonation Engine will surpass the efficiency of classical engine of comparable parameters [1]. Moreover, detonation combustion can be realized in wide range of oxidizer to fuel ratio, which can lead to reduction of temperature and toxic components of exhaust gases. The paper describes development of the Reactive Euler Flow Solver for Propulsion Systems (REFLOPS) [2] for simulations of the near wall heat transfer in the combustion chamber of the Rotating Detonation Engine. High – order accurate techniques applied for solving reactive, full Navier Stokes equations are described, and validation of the code on numerous test cases is presented. Features of the near wall reactive flow are analysed, and mechanisms of the heat transfer are discussed.
