Blowing ratio
WebSep 22, 2024 · The numerical study is extended for various injection locations with a wide range of operating parameters such as blowing ratios from (0.25–3), density ratios (1.095, 2.5, and 4), and different pressure ratios from 1 to 15, representing the operating conditions of an actual aero-engine afterburner. WebApr 1, 2024 · At a low blowing ratio ( Fig. 2 (a)) the mainstream covers the upstream part of the hole and lifts over the jet, helpful for pushing the jet towards the film-cooled wall. While at a high blowing ratio ( Fig. 2 (b)) the jet is only weakly affected by the mainstream and shows a strong penetration into the mainstream before it is bent over.
