dc.description.abstractThis thesis presents a computational analysis for determining the flow properties of novel non-circular nozzles. In last few decades, non-circular nozzles have been investigated intensively due to their remarkably superior capabilities in enhancing mass entrainment over circular nozzles. In this thesis, to increase the amount of ambient fluid entrained in the jet flow, three different geometrical modifications are applied to non-circular nozzles. These modifications include changing contraction profiles, the twist angles of transition, and nozzle lengths. The flow properties of air emanating from geometrically modified non-circular nozzles are studied by using computational fluid dynamics (CFD) in the Star CCM+ fluid solver. This computational analysis shows that suitably modified non-circular nozzles are very effective passive flow conditioning devices and can modify the flow field. Particularly, nozzle with a sharp exit and large twist angle entrains the ambient fluid at a higher rate than the circular and other modified non-circular nozzles.
