Ebrahim Ghahramani studies cavitation modelling in his PhD. The aim is to develop a hybrid Eulerian mixture – Lagrangian bubble solver to improve the resolution of various scales of cavity structures. In this model, the larger cavities are considered in the Eulerian framework and the sub-grid structures are tracked as Lagrangian bubbles. The hybrid solver will be an efficient tool for real case problems and addresses the issues with Eulerian models in cavitation inception and bubble collapse. The project is a part of H2020 CaFE ITN project and also in collaboration with Chalmers UTC. Ebrahim Ghahramani has academic background in Fluid Mechanics and his research interests include CFD, Multiphase flows, Biomedical engineering and Turbulence Modeling.
