A non-return valve is a valve that allows the direction of fluid flow only in one direction. Non-return valve plays a marginal role in pumping systems to avoid initial priming of pump set. The overall efficiency of pump system is much dependent on the foot valve. Since the efficiency of the whole system is reduced, when the starting stage (foot valve) is less effective. The traditional model non return valve is having more resistance to fluid flow due to its inefficient design and manufacturing [1]. In this study, modelling and analysis of commercial flap nonreturn valve are done. The study was focused on finding the weak points of the foot valve. CREO Parametric 2.0 and ANSYS® CFD packages were used in this study. The various parameters analyzed during this analysis are flow pattern, velocity streamlines, pressure contours, turbulence etc.. The model and analysis of commercial flap non-return valve is performed on CFD software.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
