Nanowires for Enhanced Boiling Heat Transfer
Nano Letters, 2009Boiling is a common mechanism for liquid-vapor phase transition and is widely exploited in power generation and refrigeration devices and systems. The efficacy of boiling heat transfer is characterized by two parameters: (a) heat transfer coefficient (HTC) or the thermal conductance; (b) the critical heat flux (CHF) limit that demarcates the transition

Enhancement of heat transfer in stokes flows
2017 IEEE 56th Annual Conference on Decision and Control (CDC), 2017We discuss the optimal control problem of enhancing heat transfer between two fluids via controlling the velocity of the cold fluid flow. In this paper, we consider that the fluid flow for cooling the hot fluid is a Stokes fluid flow induced by the boundary control inputs through the Navier slip boundary conditions.

MHD enhanced nanofluid mediated heat transfer in porous metal for CPU cooling
, 2020In this study, impingement cooling of a porous metal CPU cooler saturated with nanofluid under the effects of magnetic field was modeled analytically. Darcy-Brinkman-Forchheimer model and viscous dissipation effect were considered to simulate fluid flow ...
