<p> An experimental study of the flow phenomena occurring in jet-driven vortex flows was undertaken. Two vortex chambers were constructed, one using compressed air, the other using water as the working fluid. Temperatures and total and static pressures were measured at several locations in the air-driven vortex chamber, and the wall static pressure, temperature and Mach number distributions for the vortex were presented for different exit geometries and mass flow rates. A comparison of some indicative experimental results was made with the present vortex theory. </p> / Thesis / Master of Engineering (MEngr)
