چکیده
Trapezoidal grooves were arranged in channel sidewalls of the proposed micro-channel heat sinks to enhance transfer for cooling microelectronic systems. The 3-D numerical simulations carried out investigate characteristics fluid-flow and micro-channels. Field structures thermal fluid-flow, Nusselt number, friction factor, f, employed study effects relative groove depth, ?, spacing length, trapezoidal on hydraulic performance results showed that presented better flow than smooth straight one Re <597.74 with f/f0 < 1 >149.44 Nu/Nu0 > 1, respectively. enhancement was achieved up 1.197 ? = 0.4 714.18. Furthermore, depth had much more significant influence overall length.

Effects of Slip and Heat Transfer on MHD Peristaltic Flow in An Inclined Asymmetric Channel
Peristaltic transport of an incompressible electrically conducting viscous fluid in an inclined planar asymmetric channel is studied. The asymmetry is produced by choosing the peristaltic wave train on the walls to have different amplitude and phase. The closed form solutions of momentum and energy equation in presence of viscous dissipation term are obtained for long wave length and low Reynol...
متن کاملFluid Flow and Heat Transfer of Nanofluids over a Flat Plate with Conjugate Heat Transfer
The falling and settling of solid particles in gases and liquids is a natural phenomenon happens in many industrial processes. This phenomenon has altered pure forced convection to a combination of heat conduction and heat convection in a flow over a plate. In this paper, the coupling of conduction (inside the plate) and forced convection of a non-homogeneous nanofluid flow (over a flat plate) ...
متن کاملThree-dimensional analysis of heat transfer in a micro-heat sink with single phase flow
A detailed numerical simulation of forced convection heat transfer occurring in silicon-based microchannel heat sinks has been conducted using a simplified three-dimensional conjugate heat transfer model (2D fluid flow and 3D heat transfer). The micro-heat sink model consists of a 10 mm long silicon substrate, with rectangular microchannels, 57 lm wide and 180 lm deep, fabricated along the enti...
متن کاملStudy on Thermal and Hydrodynamic Indexes of a Nanofluid Flow in a Micro Heat Sink
The paper numerically presents laminar forced convection of a nanofluid flowing in a duct at microscale. Results were compared with both analytical and experimental data and observed good concordance with previous studies available in the literature. Influences of Brinkman and Reynolds number on thermal and hydrodynamic indexes have been investigated. For a given nanofluid, no change in efficie...
متن کاملTwo-phase flow in high-heat-flux micro-channel heat sink for refrigeration cooling applications: Part II—heat transfer characteristics
This paper is the second of a two-part study concerning two-phase flow and heat transfer characteristics of R134a in a micro-channel heat sink incorporated as an evaporator in a refrigeration cycle. Boiling heat transfer coefficients were measured by controlling heat flux (q00 = 15.9 93.8W/cm) and vapor quality (xe = 0.26 0.87) over a broad range of mass velocity. While prior studies point to e...
