  • PHE-22 CFD Simulations of a Plate-and-shell Heat Exchanger

    December 04, 2019
    HTRI experimentally evaluated the thermal-hydraulic performance of a water-water plate-and-shell heat exchanger at the Research & Technology Center and then used the results to calibrate a solution approach through computational fluid dynamics. The tortuous flow paths through the corrugated channels of the plate pack were modeled effectively using porous media. Inertial resistance...
