Indoor Air Quality (IAQ) and Thermal Comfort Studies in Indoor Environments

The quality of air and level of thermal comfort inside an indoor environment are a major concern due to their effects on occupants. Individuals with prolonged exposure to indoor air pollutants may induce health damage while poor thermal comfort level leads to less productivity. The purpose of carrying out the studies are to investigate the effects of critical parameters on air pollutants and properties inside several indoor environments, which includes an operating room, a mosque and a bus passenger compartment. A CFD approach is used for achieving the research aims. A proper ventilation system strategy for reducing contaminants concentration and improving the thermal comfort level are defined.

Inertial Microfluidics Technique for Rare Biological Cells Separation

Inertial microfluidics as passive technology for Lab-on-chip (LOC) high throughput biological cells separation is able to be demonstrated using simple microchannel structure design. However, the quantitative design rules between inertial microfluidics and microchannel geometry in separating rare biological cell i.e. viruses, bacteria, tumor cell are still lacking. Therefore, inertial microfluidics phenomena including inertial migration and secondary flow formation with various microchannel geometries are currently being investigated. Theoretical, numerical and experimental methodologies are being employed in the study on the way to enhance the knowledge on the mechanism and physics of inertial microfluidics with microchannel geometries.
