Abstract
Numerical simulations are carried out to analyse the cavitating effects over the circular disk cavitator and cone cavitator. The commercial software tool ANSYS Fluent 16 was used to simplify two dimensional Reynolds averaged Navier Stokes equation with the compressible fluid flow by considering the pressure-based solver with standard K- ω turbulence model. The Schnerr and Sauer cavitation model is employed to study the cavitation phenomena. The simulations are done by varying the diameter of circular disk and cone cavitator, by varying fixed cavitation numbers and by varying flow pressures. Initially flow past circular cavitator will be analysed by varying the cavity length and validated with other existing models [i.e., Kunz cavitation and full cavitation model]. Simultaneously, to analyse the capability and robustness of the computational analysis cone cavitator are adopted. The obtained results from the simulation are then validated with the experimental and theoretical correlations.
