Abstract

•ESTS lobed nozzle, chevron, beveled and conical nozzle of Mach 1.80 are compared.•Acetone PLIF, centerline pitot measurements and CFD computations are conducted.•Mixing enhancement is 430% in ESTS nozzle, chevron (222%) and beveled (138%).•Streamwise vorticity production is widespread in ESTS lobed nozzle.•Mechanism of vorticity production in ESTS nozzle is explained for the first time.
