  1. Simulation and design of microfluidic lab-on-chip systems Investigator: Ludwig C. Nitsche, Chemical Engineering Department Prime Grant Support: USIA Fulbright Commission • Develop fast, predictive computer modeling capability for droplet formation, motion, mixing and reaction in micro-channels and lab-on-chip systems. • Merge continuum hydrodynamic models with molecular dynamics for nano-fluidic applications. • Design and optimize m-unit-operations for sensors and chemical analysis. Surface wetting Wavelet compression Of hydrodynamic Information for fast summations Hydrodynamic Interaction kernel • “Smart swarms” of particles automatically solve for low-Reynolds-number fluid dynamics and catastrophic evolutions of phase and surface geometry (surface wetting, coalescence, rupture, reaction). • Hydrodynamic interaction kernels and interfacial forces can be extended to include molecular effects. • Wavelet compression of summations vastly increases computational speed. • Developed novel cohesive chemical potential that models interfaces more simply than previous volumetric formulations and also includes diffusion. • Treated surface wetting and contact angles through suitable adhesive force laws. • Development of simulations of lab-on-chip assay and sensor reactions is underway.
