Abstract

This study is a numerical analysis of the flow characteristic of a quick coupler. The quick coupler is a popular coupling tool for pipelines in hydraulic and pneumatic systems. In this study, the flow characteristic of a quick coupler outlet is conducted about the flow coefficient. The quick coupler is analyzed for improving flow and confirmed with the study results. The velocities with pressure distribution according to inlet and outlet pressure drop of the coupler are also compared. The flow coefficient is analyzed according to the flow analysis result for each pressure drop. When the pressure drop is 1 psi, the flow coefficient (Cv) matched about 98% of the value provided by the actual product.
