Numerical modelling of tidal flows around headlands and islands
… a study of tidal flow interaction with headland and island features. Wake development in the lee of topographic features can generate complex two- and three-dimensional flow structures. The primary objectives of the research are to (i) determine the suitability of traditional numerical …

Effect of impeller submergence on power dissipation and solids suspension in mixing systems equipped with pitch-blade turbines
Mixing and dispersion of solids in a liquid is a process frequently encountered in the pharmaceutical industry and often conducted in cylindrical baffled tanks stirred by mechanical impellers. In operations where the liquid level is decreased (as often which emptying the tank) the process must be …

Imaging through optical multimode fiber: towards ultra-thin endoscopy
… information with high resolution, high speed, and minimal invasiveness. Endoscopy in particular has revolutionized healthcare diagnosis and treatment as well as biological research by offering visual access to otherwise unreachable remote tissues. However, existing endoscopic modalities face …

Ultrasonically Assisted Single Screw Extrusion, Film Blowing and Film Casting of LLDPE/Clay and PA6/Clay Nanocomposites
… the effect of ultrasonic treatment on the dispersion of modified clay particles in LLDPE and PA6 matrices and the final properties of nanocomposites. LLDPE and PA6 are two polymers that are widely used in packaging industry. Blown and cast films were manufactured from the prepared …

Mixing in axisymmetric gravity currents and volcanic conduits
The first part of this thesis investigates the mixing of ambient fluid into axisymmetric high Reynolds number gravity currents. A series of laboratory experiments were conducted in which small scale gravity currents travelled along a wedge shaped channel with an increasing width in the downstream …
