Abstract | A supersonic flow over an axisymmetric backward facing step model with and without a hydrogen jet was investigated experimentally and numerically. The hypersonic flow of Mach 3.94 was produced by the free-piston wind tunnel of University of Southern Queensland (TUSQ) and the hydrogen supply system was designed to maintain a steady injected fuel flow into the supersonic flow during the testing time. The wall pressures were measured by pressure sensor and flow field was captured using schlieren visualization technique. The FLUENT was used to simulate the model under different experimental conditions. The experiment results show that the static pressure rises due to shock came from cone’s wall strikes the cylinder’s wall and the recirculation area is formed near the location of the step. The appearance of H2 injection or the increase of the momentum of hydrogen injection will increase the static pressure of the location near the step and decrease the growth trend of pressure in the experimental and simulation results. |
