Talk Title: Interfacial thermal transport in partially porous channel flow at turbulent flow regimes
Abstract: We investigate interfacial thermal transport in a partially porous channel via laboratory experiments to evaluate the effect of porous medium microstructure at varying Reynolds numbers. Previous direct numerical simulations for partially porous channel flow indicate that large vortex structures enhance turbulent heat transfer at the porous medium-unobstructed
flow interface. Commercially-available Aluminum foams with nominal pore sizes 10 ppi and 40 ppi are attached to a heater block and placed in a forced convection arrangement adjacent to an unobstructed channel. Measurements of pressure drop and temperatures are made across the porous section for bulk Reynolds number varying from 500 to 1500 to characterize friction factors and Nusselt numbers. Heat transfer efficiency with respect
to pumping power requirements is evaluated. Particle Image Velocimetry (PIV) measurements made at a subset of these Reynolds numbers are being analyzed to test for the emergence of interfacial vortex structures, and quantify their effect on interfacial thermal transport.
Biography: Shilpa Vijay is a Ph.D. student under Professor Mitul Luhar. Her research focuses on characterizing thermal transport over porous interfaces in turbulent regimes. Shilpa has a B.S. in Civil Engineering from College of Engineering Pune in India (2016), and an M.S. in Mechanical Engineering from USC (2018).
