Atmospheric Water Harvesting

   Our group is working to develop atmospheric water harvesting (AWH) as a viable solution to industrial and domestic water requirements. On the technical front, we are developing novel water harvesting techniques that can be scaled up to produce large quantities of water.

Electrically Tunable Boiling Heat Transfer

   Boiling heat transfer has enormous impact in areas such as electronics cooling, desalination and steam generation. In practice, boiling heat transfer is limited by the formation of a vapor layer at the solid-liquid interface (Leidenfrost effect).

Control of Ice and Hydrate Nucleation

   Control of nucleation of ice and hydrates has many practical applications in the areas of power generation, oil and gas and infrastructure. Our recent efforts are targeted at isolating the effects of surface chemistry, fluid composition and electric fields on the nucleation kinetics of ice and methane hydrates.

Electrical Mitigation of Hydrocarbon Fouling 

   Our group is working on the development of the first ever electrical technology for hydrocarbon fouling mitigation. The underlying concept is the electrowetting of the target surface with water, which reduces the possibility of hydrocarbon deposition on the surface. Buildup of a water layer at the surface prevents hydrocarbon-surface contact.

Electrical Heat Pipes for Extended Distance Heat Transport

   Current electronics cooling strategies are quickly becoming insufficient to meet the ever-growing needs of technology. Heat pipes are advantageous because they operate passively by cyclically evaporating and condensing a working fluid, but they are limited by the maximum fluid velocity their internal wick can sustain.

Mist-based Cooling for Power Plants

   Our group is working on the development of a novel mist-based cooling concept to reduce the water consumption and increase the electricity output of power plants. The concept involves the use of water-based mists to reject heat to near wet bulb temperatures.
