Predictions of Axial and Transverse Injection into Supersonic Flow

Abstract

CFD calculations are performed on a swept ramp injecting fuelaxially, and on a two-hole transverse fuel injection downstream of abackward-facing step, both into a supersonic turbulent flow. Theresulting complex flowfields are predicted using a cubick–ε turbulence closure. Comparisons with experimental data show very good agreement. A discussion of the main flow features is presented. The fast computational convergence demonstrates the readiness of the method for the design cycle.
