Experimental and Numerical Investigations of a Bypass Dual Throat Nozzle
Journal of Engineering for Gas Turbines and Power, 2014 The bypass dual throat nozzle (BDTN) is a new kind of fluidic vectoring nozzle. A bypass is set between the upstream convergent section and upstream minimum area based on the conventional dual throat nozzle (DTN). The BDTN shows a minimum or even no penalty on the nozzle's thrust performance, while it would be able to produce steady and efficient ...
