Thermal/Fluid Sciences: environmental and multiphase transport phenomena
The research interests of our group focus on multiphase, complex-fluid, turbulent/chaotic and environmental systems. Studies range from nanoscale problems, e.g. spinodal decomposition in shear flows, coalescence, and flow interactions with macromolecular structures like cell-membrane receptors and channels, to macroscale problems like turbulent transport processes at the air-sea interface, of importance in global warming. Some applications are to a environmental processes, development of complex/multiphase fluid formulations, and mesoscale transport phenomena in biological systems. An example of work in the last area is transport and transduction processes in neo-vascularization.
Experimental techniques involve Laser-Doppler Anemometry, Particle Imaging Velocimetry, as well as flow and molecule-specific imaging based on Atomic Force Microscopy. Simulation/theoretical approaches are based on spectral methods using level-set and self-consistent field theory (SCFT) models. We, together with Profs. Frederickson and Ceniceros, have founded the Complex Fluids Design Center (CFDC) at UCSB. The work is supported by DOE Basic Energy Sciences, the National Science Foundation, NASA, Los Alamos National Laboratories and several industrial organizations.
