Numerical Investigation on the three-Dimensional Flowfield in the Single Expansion Ramp Nozzle with Passive Cavity Flow Control

Abstract: Single Expansion Ramp Nozzle (SERN) with large expansion ratio is normally adopted for the hypersonic aircraft in consideration of integrated aircraft / propulsion system / nozzle design. Under low Mach number and low Nozzle Pressure Ratio (NPR, the ratio of inlet total pressure to outlet static pressure) conditions, the flow in the SERN is a state of severe over-expansion, the internal resistance increased obviously, the flow quality and performance of the SERN sharply deteriorated. How to effectively improve… Show more

“…However, they increase the complexity and weight of the nozzle's mechanical structure and reduce its operational reliability. Flow control techniques offer various active and passive flow control measures (Gronland and Berens 1995;Asbury et al 1996;Tsunoda et al 2000;Gamble and Haid 2004;Hao and Wang 2009;Zhou et al 2016;Zhou and Wang 2019), with secondary injection and synthetic jet actuators (SJA) being the most-used active measures. Lv et al (2017b) performed numerical simulations using a two-dimensional (2D) SERN model with cowl-based secondary injection.…”

“…The supersonic inlet is an air-intake part of the scramjet engine responsible for capturing, slowing down and compressing the incoming air for downstream combustion (Billig 2008;Balent and Kutschenreuter 1965;Jayakrishnan and Deepu 2021;Senthilkumar and Muruganandam 2020;Zhou and Wang 2019). The inlets must operate in the started mode for proper function.…”
