1. Fluid Mechanics of Vertical Axis Turbines : Simulations and Model Development
Abstract : Two computationally fast fluid mechanical models for vertical axis turbines are the streamtube and the vortex model. The streamtube model is the fastest, allowing three-dimensional modeling of the turbine, but lacks a proper time-dependent description of the flow through the turbine. READ MORE

3. A Realizable Hybrid Mixture-Bubble Model for Cavitating Flows
Abstract : Cavitating multi-phase flows include an extensive range of cavity structures with different length scales, from micro bubbles to large sheet cavities that may fully cover the surface of a device. To avoid high computational expenses, incompressible transport equation models are considered a practical option for simulation of large scale cavitating flows, normally with limited representation of the small scale vapour structures.

4. Numerical simulation and analysis of multi-scale cavitating flows using a hybrid mixture-bubble model
Abstract : The aim of this research is to model and analyse multi-scale cavitating flows with a certain emphasis on small sub-grid vapour structures. Cavitating flows include vapour structures with different length scales, from micro-bubbles to large cavities. READ MORE
