Continuum mechanics

Continuum Mechanics research in Birmingham covers several broad areas with the main emphasis on the following research directions:

-  Nonlinear wave dynamics of thin films and flows on flexible substrates
-  Nonlinear dynamics of bubbles and drops
-  Dynamic wetting phenomena and flows over chemically-patterned surfaces
-  Nonlinear flow dynamics in microchannels
-  Formation of singularities in convergent free-surface flows
Fluid flows with transitions in the topology of the flow domains
-  Wetting fronts in porous media and flow dynamics on porous substrates
-  Mass and heat transfer in chemical engineering
Hypersonic boundary layers on porous and compliant walls
-  Nonlinear instabilities of boundary layers and curved compressible wakes
-  Optimization of fuel cells
-  Dissolved air flotation and convective fluid flows
-  Bifurcation theory, attractors and surface turbulence
-  Homoclinic and heteroclinic trajectories in dynamical systems generated by the
   Navier-Stokes equations
-  Computational fluid mechanics and development of problem-oriented numerical
-  Pattern recognition and its application to fluid dynamics

The research interests of the members of the group are given below.
