“…Numerical simulations were tried at Mach 5 and Mach 6, the results being compromised by burning across the entire intake channel, total firing corresponding to the 15° value, which determines a larger angle of impact wave with implications for upstream self-ignition. As in the previous article [10], the initial analysis data is those in Table 1. For CFD 2D flow analysis, Ansys Fluent 18 [16] and simple geometry of the PDE propulsion system were used with the initial conditions in Table 1 for stoichiometric firing.…”
