Key Researchers : Assoc. Prof. Dr. Sivakumar Kumaresan, Dr. Abu Zahrim Yaser, Dr. Tham Heng Jin, Dr. Md. Mizanur Rahman and Mr. Mohd Suffian Misaran @ Misran

The aim of this project is to enhance the drying rate of seaweed through the enhancement of flow rate by natural convection processes. Therefore, to achieve this aim currently the research group members are focusing on the design and construct a solar dryer with chimney for experimental study. Under this project drying behaviour of solar dryer with chimney with different configuration will be studied to optimize the configuration of the chimney.

Most of the maritime industries are utilized the metallic materials for underwater propeller construction. However, metallic materials are not always an ideal material as it is not chemically or environmentally resistant and susceptible to corrosion and erosion, costly for production, and etc.   Preliminary research on advanced composite materials as a replacement for the metallic material has been carried out. The GFRP composite material has been successfully used in the complex helicoidal marine propeller blade fabrication. Through a closed-moulding designed for hand lay-up lamination, single detachable low skew GFRP composite propeller blade has been developed.

Small amounts of volatile organic compounds (VOCs) are usually present in groundwater as well as in wastewater. The examples of VOCs are trichloroethylene, methanol, benzene, toluene, ammonia, xylene, etc. which are discharged directly from industries into the water bodies. These VOCs are toxic to the aquatic life and to disturb the ecology system. Therefore this research is focused on synthesizing a suitable membrane to remove the VOCs, i.e ammonia. The high resistance of membrane to the gas removal remains a challenging task in the membrane synthesis.

           Project:   Marine Propeller Cavitation Phenomena

Underwater Research Laboratory

Cavitation is a phenomenon of nucleation, growth and implosion of vapour cavities in liquid form as static pressure is reduced below the vapour pressure. The marine propeller cavitation can appear in a pattern of sheet, bubble, cloud, tip vortex or hub vortex cavitation that is influenced by the local pressure distribution and flow.   Cavitation cannot be eliminated but can be delayed or minimized to reduce detrimental effects.

The GPS Enabled Driver Alert System (DAS) promotes safety driving through consistent physical conditions monitoring, including capturing the inattention of the driver to help keeping him/her staying awake while driving. DAS is an interactive personalized tool that “understands” the real conditions of the driver through data fusion techniques, sensing devices, and Android-based smartphone application to hinder the potential harm of accident such as unnecessary property damages, legal penalties, and fatal injuries.
