A new research direction in our group is mesoscale modeling
of fluids. The goal of this research is to develop
computationally tractable simulation methods that provide new
capabilities for probing important fluid transport phenomena
at the subcontinuum level. Work in this area includes the
General Framework for Dissipative Particle Dynamics
Simulations of Multicomponent Fluids
We have developed a general framework for mesoscopic particle
based transport simulations of flow and heat transfer in
multicomponent fluids. This framework, based on the
dissipative particle dynamics approach, accounts for
important contributions to the dynamic response not
accessible at the typical length and time scales used in
molecular dynamics simulations. These contributions include
hydrodynamic coupling between the fluid and the suspended
phase and thermal fluctuations at mesoscopic scales.
Nano-Textured Surfaces for Enhanced Heat Transfer at the
We have recently begun a new project whose goal is to
investigate phase change heat transfer enhancement at
surfaces with nanometer-scale patterns. To do this, we are
establishing new multiscale simulation approaches to enable
'visualization' of boiling processes at an unprecedented
level of spatial detail. The target application of this
project is thermal management of high heat flux electronics.
