Abstract
Nozzles are key components in many engineering applications that involve fluid flow, such as propulsion systems and industrial processes. Nozzle efficiency, defined as the ratio of actual outlet velocity to ideal outlet velocity, significantly impacts system performance. This paper evaluates the key variables that can affect nozzle efficiency, including nozzle geometry, Reynolds number, Mach number, turbulence, surface roughness, and flow non-uniformities. Experimental data from previous studies are reviewed and analyzed to quantify the impact of each variable. Computational fluid dynamics simulations are also performed to visualize flow behaviours. The results provide insight into nozzle design optimization and selection of operating conditions to maximize efficiency. Overall, this work identifies the critical factors engineering designers should consider to achieve high nozzle performance.
