Understanding of extensional flow mechanism is utmost important for the efficient operation of many industrial processing such as fiber spinning, extrusion, injection molding, and electrospinning, particularly if these involve non-Newtonian fluids such as polymer fluids, gels, f…

A numerical model was developed on the basis of SOLA-VOF algorithm to study the impact and solidification of a liquid droplet upon its impingement on a substrate. The model, in general, is applicable to transient fluid flows and heat transfer including two moving boundaries: a l…
This research is concerned with the development of a mathematical approach for energy and mass transport in solidification modelling involving a control volume (CV) technique and finite element method (FEM) and incorporating non-physical variables in its solution. The former tec…
Phase change in solidification and melting can be described with the aid of discontinuous functions. The aim of this project is to establish effective methodologies for the solution of discontinuous phase-change problems. The classic capacitance method, which distributes the eff…
Modelling the ice accretion in glaze regime for the supercooled large droplets is one of the most challenging problems in the aircraft icing field. The difficulties are related to the presence of the liquid water film on the surface in the glaze regime and also the phenomena ass…
A wide variety of products are now made of metal alloys. The superior properties of these alloys permit products to be used in very demanding environments where other materials would fail. The major quality issues for these alloys are melt-related defects, such as segregation de…
The addition of a thermal energy storage (TES) into a process allows the operator to store and release thermal energy on demand. This increased process flexibility leads to potential benefits such as shifting energy demand from peak to off-peak hours. In particular, so called ph…
In continuous casting, longitudinal cracks and depressions are some of the most dangerous defects in the cast product. Cracks and depressions can lead to substantial mitigation costs or sudden failures in the final product, and in the worst case can lead to catastrophic breakout…
Alloy castings are usually solidified with a coarse columnar grain structure under normal casting conditions unless the mode of the solidification is carefully controlled. It is desirable for the grain structure to be fine and equiaxed to improve their mechanical performance as …
