Determination of wall pressure flows at supersonic Mach numbers

This article investigates the wall pressure dissemination on a circular duct when flow is exhausted into CD nozzle. study aims at to scrutinize static and its growth control activated. The microjets are employed base pitch circle radius (PCR) of 6.5 mm, 0.5 mm. Mach numbers area ratio used 2.56, (M) 2 3. lift diameter (L/D) nozzle (NPR) were from L/D = 10 1 NPRs 3 11. tested different expansion level for M 2. oscillations in field seen they under expanded, this trend continues total length pipe. When nozzles ideally expanded absent as NPR only waves will be present. Similar trends also well whenever there an adverse gradient With decline pipe length, wavy nature getting died out, recovery smooth. backpressure has crucial role play dictating magnitude pressure. seems sufficient continue remain committed with pipe, whereas lowest size required 4.
