1. Study of generation, growth and breakdown of streamwise streaks in a Blasius boundary layer
Abstract : Transition from laminar to turbulent flow has beentraditionally studied in terms of exponentially growingeigensolutions to the linearized disturbance equations.However, experimental findings show that transition may occuralso for parameters combinations such that these eigensolutionsare damped.

2. Numerical studies of bypass transition in the Blasius boundary layer
Abstract : Experimental findings show that transition from laminar toturbulent ow may occur also if the exponentially growingperturbations, eigensolutions to the linearised disturbanceequations, are damped. An alternative non-modal growthmechanism has been recently identi fied, also based on thelinear approximation. READ MORE

3. Numerical study of particle suspensions in Newtonian and non-Newtonian fluids
Abstract : Solid or deformable particles suspended in a viscous fluid are of scientific and technological interest in a broad range of applications. Pyroclastic flows from volcanoes, sedimentation flows in river bed, food industries, oil-well drilling, as well as blood flow in the human body and the motion of suspended micro-organisms in water (like plankton) are among the possible examples.

4. Simulation of deformable objects transported in fluid flow
Abstract : Deformable particles suspended in a viscous fluid can be found in many industrial and biological applications. In this thesis, two different numerical tools have been developed to simulate suspensions of capsules, thin membranes enclosing a second fluid and a rigid nucleus so to work as model for ”Eukaryotic” cells, and flexible slender bodies known as filaments/fibres.

5. Point of care microfluidic tool development for resource limited settings
Abstract : The development of point of care diagnostics using recent advances in microfluidics have the potential to transform health care in several ways, especially in resource limited settings with limited access to advanced health care infrastructure. However, translating a point of care device to reality is often a challenging task because of the complexities involved in integrating a number of diverse engineering concepts into an easy to use, accurate and portable device.
