RESEARCH

The group works on a wide range of projects all under the common umbrella of fluid problems at small length and time scale. The research includes, theoretical, computational, and experimental aspects.

Supersonic Retropropulsion

Supersonic retropropulsion is a cutting-edge space exploration technique involving the firing of rockets in the opposite direction of a spacecraft’s motion during descent through a planet’s atmosphere. This innovative approach helps decelerate and control spacecraft in a supersonic regime, enabling precise landings on celestial bodies with atmospheres, such as Mars, by utilizing aerodynamic drag and propulsion simultaneously.

Boundary conditions

Velocity boundary conditions in fluids define the behavior of fluid motion at the interface of a solid surface, specifying how the fluid velocity and its derivatives relate to the properties of the surface. These conditions play a crucial role in fluid dynamics simulations, guiding the interaction between fluids and solid boundaries in applications ranging from aerodynamics to fluid transport systems.

Bubble dynamics at nanoscale

Bubble dynamics and cavitation describe the formation, growth, and collapse of gas or vapor-filled bubbles in a liquid, often resulting in intense localized pressures and temperatures. These phenomena have diverse applications, from cleaning processes like ultrasonic cleaning to the detrimental effects on machinery caused by cavitation erosion in fluid systems.

Engineered Living metaSurface (ELviS)

Engineering a living surface by manipulating the growth of microbes. The aim is to create microstructures out of biofilm formed by beneficial microbes. This can lead to surface modifications hese conditions play a crucial role in fluid dynamics simulations, guiding the interaction between fluids and solid boundaries in applications ranging from aerodynamics to fluid transport systems.

Supersonic flow characterization

Supersonic flows are characterized by the presence of shockwaves, abrupt changes in pressure, temperature, and density that result from the exceeding of local sonic speeds. These shockwaves play a crucial role in aerodynamics, propulsion systems, and astrophysics, influencing the behavior and efficiency of supersonic vehicles and celestial objects.

Laser ablation

Laser ablation is a process where intense laser beams are used to remove or vaporize material from a solid surface, commonly employed in applications such as material analysis, surgery, and microfabrication. This precise and controlled technique finds use in various fields, from removing unwanted tissue in medical procedures to precisely shaping materials in manufacturing processes.
