Abstract
The present study involves experimental and numerical investigations of laminar forced convection in parallel microchannel heat sink accompanied with heat spreader of size 30 mm2. Water and reduced graphene oxide nanofluid of 0.07-0.12 vf % is used as working fluid. The numerical study is performed by incorporating the thermo physical properties of reduced graphene oxide nanofluid for different Reynolds number (Re) ranging from 150 to 360 for a constant heat flux of 35 W/cm2. Additionally, studies on migration of hotspot with heat spreader from the bottom of the heat sink under varying Reynolds number are also discussed. � 2018 IEEE.
