Abstract
The characteristics of flow through the fluid flow system largely depends on the control valves and their performance. Ball valves are one among the major valves widely used in various industries due to their simple construction and ease of manufacturing. Thus investigating flow characteristics of these valves is most essential to minimize the losses due to friction and cavitation caused within the valve body. The main objective of the current work is to carry out the computational fluid dynamics analysis using Ansys® Fluent® as solver and Solidworks® as 3D modelling tools to investigate the flow patterns through the single piece ball valve to determine the various flow characteristic and there by suggest design optimization for improved flow rate and performance. Various designs of ball valve such as BVD1, BVD2 and BVD3 were tested through CFD simulation. The simulation results reveals that BVD1 and BVD2 are failed in bidirectional flow characteristics. However BVD3 shows the significant improvement in all the flow characteristics.
