Poroelastic materials in moving fluids

Poroelastic materials are ubiquitous in nature as well as engineering. We want to understand how complex poroelastic materials interact with a moving fluid. Read more... 


 

Turbulence over hairy surfaces

Fur of animals, forests and lateral line of fishes all have a filamentous, or hairy, structure. We want to understand how surfaces covered in hairs modify turbulence. Read more... 


 

Rough wall turbulence

Non-smooth rough walls appear in engineering applications such as gas turbine blades and ice-deposited airplane wings. We want to understand the connection between roughness topography and the turbulent flow around them.  Read more... 


 

Dynamic wetting on non-smooth surfaces

Wetting is observed in our daily life. Few notable examples are coffee stains and droplets on windshields. We investigate wetting dynamics on complex textured surfaces by combining experimental observations and numerical simulations.  Read more... 


 

Lubrication with poroelastic surfaces

We want to understand how porous and elastic surfaces interact with overlying particles separated by a thin layer of liquid. Red blood cells are an excellent example of the interaction between poroelastic surfaces and particles.  Read more... 


 

Physics of submerged superhydrophobicity

Some plants, for example the Salivina plant,  have surface textures that are able to preserve the air layer deep under water for a long time. Inspired by this, we want to understand how elasticity, texture topology and chemical inhomogenity can be combined to design robust air-preserving surfaces.  Read more...
