Research interests

Dr Kapil Chauhan's research examines how fluids such as water and air flow over various surfaces under different conditions. The resulting increase in understanding will lead to faster, cheaper and 'greener' transport; lower pollution in residential areas; and smaller carbon footprints for high-rise buildings.

"My research involves examining fluid flow, primarily of air and water. In particular, I investigate the boundary layer, which is a thin layer of fluid flowing adjacent to a surface.

"Almost all boundary layers in engineering applications are turbulent, meaning that the flow is characterised by random or chaotic behaviour. Turbulence is almost everywhere around us, and affects many important aspect of our lives. A better understanding of turbulence can lead us to design fuel-efficient aircraft, ships and land vehicles, better predict atmospheric flows and weather, and develop more sustainable infrastructure.

"I study various aspects of turbulence that are relevant to urban living, such as drag, dispersion and entrainment.

"Reducing the drag that occurs within the boundary layer as aircrafts and ships move through air or water can lead to significant savings in fuel costs and make transport faster and more environmentally friendly.

"Dispersion and entrainment are responsible for the transport of pollutants. Being able to predict dispersion in urban flows is important for the planning and development of residential and industrial areas.

"My research also has applications in natural ventilation, where solar energy is used to passively cool high-rise buildings, reducing the building's carbon footprint.

"The complexity of turbulent flows is what drives my passion to understand their behaviour.

"I have been studying turbulent boundary layers for more than 14 years. Since I joined the University of Sydney in early 2015, the wide array of experimental facilities and academic expertise available has expanded my area of research and encouraged me to examine new problems in natural ventilation and water quality."
