2. Studies of Transient and Pulsating flows with application to Hydropower
Abstract : The rotational motion of a hydraulic turbine runner makes pulsating flows ubiquitous in different locations of the machine. The cyclic loading thus induced may generate large pressure forces acting periodically on both stationary and rotating parts. READ MORE

3. Blood Flow variations in Large Arteries due to non-Newtonian rheology
Abstract : The blood is a complex fluid that contains, in addition to water, cells, macro-molecules and a large number of smaller molecules. The physical properties of the blood are therefore the result of non-linear interactions of its constituents, which are influenced by the local flow field conditions. READ MORE

4. Effects of boundary conditions and unsteadiness on draft tube flow
Abstract : The present research focuses on flow properties of the elbow draft tube. This element has a major function in low head turbines, since up to half of the losses may arise there at part load. The use of computational fluid dynamic (CFD) to redisign a draft tube necessitates detailed knowledged of the boundary conditions. READ MORE
