Original Abstract

The following study is focused on the flow analysis within the concentric in-line check valve. In-line check valve is part of the pipe and shut off the stream of fluid. In case that backflow occurs on the downstream side, the valve is fully or partially lifted and then abruptly closes. This effect brings undesirable pressure shocks in the entire system. The study therefore deals with the CFD analysis of steady and unsteady flow with respect to velocity and pressure field. Especially unsteady calculation mode reflects the influence of local inertial acceleration acting on the fluid and on the valve. Analysis is complemented by equation of motion of a valve which interacts with the fluid.
