INVESTIGATION OF HYDRAULIC PERFORMANCE OF A FLAP TYPE CHECK VALVE USING CFD AND EXPERIMENTAL TECHNIQUE

An attempt has been made to simulate flow through an 820 check valve by using CFD. with different flow velocities. The pressure drops ( (V) are used to determine t obtained analytical values of “K The computational analysis has been carried out at five different disc angles of check valve i.e. for 54° (fully opened), 46°, 34°, 24°, 10°. The pressure drops ( pressure loss coefficient (K experimental values. The obtained numerical results are in close agreement with experimental values, for higher design is modeled and tested in the laboratory which has shown a 10% of pressure loss in the valve.
