Valves control the fluid flow and pressure in a system or a process. Globe valves have good throttling ability, which permits its use in regulating flows. Detailed understanding of flow in Globe valve with cage apertures of various shapes and its impact on the flow characteristics and optimization was carried out. The computational study was carried out using FLUENT, a finite volume based code. Grid sensitivity test were done and the results validated experimentally. The effect of aperture configuration on flow characteristics and valve coefficient was studied to arrive at optimum value. Valve coefficient was found to be dependent on aperture shape and is maximum for the valve with triangular shaped aperture. Methodology to improve flow performance of a globe valve with highest valve coefficient is established. © School of Engineering, Taylor’s University.
