Experimental study of convective heat transfer coefficient of MgO nanofluid in a cylindrical microchannel heat sink
Convective heat transfer of MgO-water nanofluid in a microchannel heat sink is experimentally investigated in various concentrations of 0.01, 0.05, 0.1, and 0.6 wt%. The microchannel consisted of 48 parallel rectangular cross section channels with the height of 800 µm, width of 524 µm and length of 52 mm. A well stability duration (ca. 1 month) was resulted by a 180 min ultra-sonication of the ...
متن کاملEffect of Al2O3-water nanofluid on heat transfer and pressure drop in a three-dimensional microchannel
The fluid flow and heat transfer in a three-dimensional microchannel filled with Al2O3- water nanofluid is numerically investigated. The hybrid scheme is used to discretize the convection terms and SIMPLER algorithm is adopted to couple the velocity and pressure field in the momentum equations. The thermal and flow fields were analyzed using different volume fractions of n...

متن کاملAnalysis of three-dimensional heat transfer in micro-channel heat sinks
In this study, the three-dimensional fluid flow and heat transfer in a rectangular micro-channel heat sink are analyzed numerically using water as the cooling fluid. The heat sink consists of a 1-cm silicon wafer. The micro-channels have a width of 57 lm and a depth of 180 lm, and are separated by a 43 lm wall. A numerical code based on the finite difference method and the SIMPLE algorithm is d...
متن کاملNumerical Optimization of Trapezoidal Microchannel Heat Sinks
This study presents the numerical simulation of three-dimensional incompressible steady and laminar fluid flow and conjugate heat transfer of a trapezoidal microchannel heat sink using water as a cooling fluid in a silicon substrate. Navier-Stokes equations with conjugate energy equation are discretized by finite-volume method. We perform numerical computations for a range of 50 Re 600, 0.05W ...
