Title: High flexibility analysis of biodiesel production using multi-feedstock oil

Abstract: Multi-feedstock biodiesel was purposed to overcome the shortage of single oil raw material in biodiesel production. However, the high yield of biodiesel was hardly achieved when the different types of oils was used since they have different characteristics even though the processing condition was the same. This research was aimed to evaluate the use of multi-oils with wide range of fatty acids as raw materials and its process flexibility of biodiesel production. The result shows that the multi-feedstock biodiesel have potential as an alternative energy to reduce the dependency of fossil oil. The results also showed that multi-feedstock plant of biodiesel give high flexibility to the change of raw materials and process but give different result to engine performance and emissions.

Title: Fluid Structure Interaction Modelling of Tidal Current Turbines

Abstract: In this talk, an overview will be presented on the ocean current energy and the devices for extraction of tides energy. Then a specific interest will be given to the fluid structure interaction modeling of tidal current turbines. Tidal current energy has the potential to provide a new renewable energy source to the world. Tidal energy technology has successfully gone through various development phases, with demonstration systems currently operating in relevant environments at pre-commercial and commercial scales. Tidal Current Turbines (TCTs) often derive their design principals from wind turbine design. However, there are certain key differences that needs careful consideration. The proper understanding of device behavior is necessary to make this technology cost effective and reliable.
Although RANS CFD based numerical models can model the hydrodynamic behavior of a TCT but it has the limitation that it assumes the blades to be rigid. Numerical models capable of accounting for the Fluid Structure Interaction (FSI) and hydroelastic behavior of the turbine blade can provide a better approximation of the turbine performance and near flow fields. Some FSI studies have already been conducted to gain an insight into the performance of tidal turbine. However, more such studies are still needed to further the understanding of the design and performance of turbine.
