Investigation of Interactions of Injectors and Walls in Vortex Engines, M.Sc. Thesis Sharif University of Technology ; Mozafari, Ali Asghar (Supervisor) ; Saidi, Mohammad Hassan (Co-Advisor) ; Ghafourian, Akbar (Co-Advisor)
Abstract
A new experimental setup was fabricated; equipped with an adjustable chamber’s length, with air tangentially flowing through the wall of vortex engine. In a vortex combustion chamber, the tangential inlet fuel or oxidizer creates both inner and outer vortices which are rotating in the same angular direction. Indeed, inner vortex moves from head to the end of engine in the axial direction; however, outer vortex moves in the opposite direction. This setup was fabricated to see the effect of fuel nozzle characteristics on the wall temperature of the chamber. In a vortex engine, vortices affect spray droplets and force them to have a spiral path. Moreover, relative velocity of droplets and flow...
