A novel data-driven method for augmenting turbulence modeling for unsteady cavitating flows
Dhruv Apte, Nassim Razaaly, Yuan Fang +3
Cavitation is a highly turbulent, multi-phase flow phenomenon that manifests in the form of vapor cavities as a result of a sudden drop in the liquid pressure. The phenomenon has b…
Investigation of cloud cavitating flow in a venturi using Adaptive Mesh Refinement (AMR)
Dhruv Apte, Mingming Ge, Olivier Coutier-Delgosha
Unsteady cloud cavitating flow is detrimental to the efficiency of hydraulic machinery like pumps and propellers due to the resulting side-effects of vibration, noise and erosion d…
Bubble collapse near a wall. Part 1: An experimental study on the impact of shock waves and microjet on the wall pressure
Roshan Kumar Subramanian, Zhidian Yang, Francesco Romanò +1
This study examines the pressure exerted by a cavitation bubble collapsing near a rigid wall. A laser-generated bubble in a water basin undergoes growth, collapse, second growth, a…
Numerical investigation of three-dimensional effects of cavitating flow in a venturi-type hydrodynamic cavitation reactor
Dhruv Apte, Mingming Ge, Olivier Coutier-Delgosha
The concept of Hydrodynamic Cavitation (HC) has emerged as a promising method for wastewater treatment, bio-diesel production and multiple other environmental processes with Ventur…
