Pressure-strain redistribution as the mechanism for dissimilar heat transfer under spanwise wall oscillation waveforms
Lionel Agostini, Cedric Flageul
Spanwise wall oscillation can enhance convective heat transfer disproportionately to its drag penalty, a departure from the Reynolds analogy termed dissimilar heat transfer (DHT).…

Breaking the Reynolds Analogy: Decoupling Turbulent Heat and Momentum Transport via Spanwise Wall Oscillation in Wall-Bounded Flow
Lou Guérin, Cédric Flageul, Laurent Cordier +2
This work investigates spanwise wall oscillation (SWO) as a method to preferentially enhance heat transfer over drag in turbulent channel flow. Direct numerical simulations at $Re_…
