With this blog article, Cadence would like to share some of its know-how, summarizing state-of-the-art CFD technologies for cavitation prediction and covering different applications and CFD features to answer the engineer’s needs.1 A new wave in fluid dynamics NUMECA Advanced Developments for Better ProductsĢ NUMECA International Why NUMECA? Contents PRODUCTS AutoMesh About Us NUMECA has been providing Computational Fluid Dynamics (CFD) Software, grid generation systems and consulting services worldwide since NUMECA s software systems are used for the simulation, design, and optimization of fluid flow and heat transfer. Many publications cover the subject, sometimes from another point of view, starting from cavitation inception to its actual physical modeling, using pragmatic approaches or more sophisticated models. It occurs in many sectors, such as marine propellers, hydrofoils, torpedos, pumps, etc.

Still, it is one of the most challenging topics CFD engineers must tackle. It can lead to structural damage due to the bubbles imploding when subjected to higher pressure, but it can also cause instabilities and increased noise.

How to Tackle Cavitation in Pump and Propeller Designs with CFDĬavitation is a phenomenon in which rapid changes in pressure in a fluid lead to the formation of vapor-filled cavities or bubbles in places where the pressure is relatively low.
