This study investigates the flow characteristics within a butterfly valve. Pipelines are widely used in various mechanical systems, such as vehicles and industrial processes, to transport high-pressure gases. In regions where flow within these pipelines encounters valves, substantial noise can be generated, making noise control a critical factor in assessing system quality. Therefore, accurately predicting and mitigating noise is essential. To identify the root cause of noise generation, a flow analysis is performed. Flow-induced noise is evaluated through the acoustic power level using the standard -ε turbulence model and the broadband noise source acoustic model in commercial computational fluid dynamics software. Results indicate that turbulence generated as the fluid passes through the butterfly valve is a primary source of significant noise. Consequently, this study applies chamfer processing to the butterfly valve to analyze the effect of valve shape on flow-induced noise in both straight and curved pipes. The flow analysis results confirm that chamfer processing effectively reduces noise, demonstrating the proposed valve shape’s effectiveness in mitigating flow-induced noise.
