The National Research Council of Canada (NRC) has developed a numerical model of a double-acting reciprocating pump to support the design of a wave pump for the College of the North Atlantic. A validated model could reduce design cost by reducing the number of physical models and tests. A series of validation tests with a prototype wave pump were conducted at the NRC Ocean Engineering Basin. The numerical model predicts piston motion and applied force on the piston rod; however, it does not predict cylinder pressures. Further development is needed to adapt the model for unsteady flow.
