The computational analysis of partial sheet hydrofoil
cavitation in two dimensions is performed. Particular attention is given to the method of simulating the flow at the end of the cavity. A fixed-length partially
cavitating panel method is used to predict the height
of the re-entrant jet, using the values of the cavitation number and the drag coefficient. The jet surface is subsequently constructed and included in an updated cavity
shape. A source singularity is introduced in the fluid
domain to account for the mass flux through the part of the domain boundary represented by the re-entrant jet surface. Further iterations are performed for fixed cavitation number on the cavity with a re-entrant jet cavity
termination model. This model is seen to produce good results and displays quick convergence. A validation is accomplished by conducting a parametric analysis of the model and comparing the present calculations with other
numerical schemes. The flow around the partially cavitating hydrofoil with a re-entrant jet has also been treated with a viscous/inviscid interactive method with
favourable results
