  • Conceptual model of a novel thermo-adsorptive battery for use in electric vehicles that is being developed at the MTFL in conjunction with MIT, UC Berkeley and Ford.

    Possible solutions for the heat exchanger in the thermo-adsorptive battery: (1) Porous Media-based and (2) Spray-based designs

    False color images of a droplet collision at a microfluidic Y-junction. The colors help identify the progress of mixing, where red indicates a locally mixed region and blue/cyan indicates little to no mixing.

    These images illustrate the role of convection and diffusion in mixing. Starting from the initial distribution in the upper left corner, the pixels can be convectively rearranged by 22, 24, and 26 times (upper row) or diffusively averaged 101, 103, and 104 times (left column).

    Series of high speed images (top) taken at 10,000 fps showing a droplet collision and subsequent mixing event. The image sequence corresponds to the mixing regions indicated on the statistical plot on the right.

    In the MTFL, we focus on thermal fluid problems ranging from the nanoscale to the macroscale over a wide range of applications. The overarching theme of our group is to bridge the different lengthscales, integrating nano/microscale fluidic and transport understanding and solutions into macroscale phenomena and applications. We conduct research in areas such as microfluidics, water desalination, nanopolymeric surfaces, microelectronics cooling, drag reduction and novel optical diagnostics.
