Temperature Uniformity in Cross-Flow Double-Layered Microchannel Heat Sinks

Numerical 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 ...

A Study of Critical Heat Flux during Flow Boiling in Microchannel Heat Sinks

Single-Phase Flow and Heat Transport and Pumping Considerations in Microchannel Heat Sinks

Microchannel heat sinks are widely regarded as being amongst the most effective heat removal techniques from space-constrained electronic devices. However, the fluid flow and heat transfer in microchannels is not fully understood. The pumping requirements for flow through microchannels are also very high and none of the micropumps in the literature are truly suitable for this application. Resul...

Multi-objective optimization of nanofluid flow in microchannel heat sinks with triangular ribs using CFD and genetic algorithms

Abstract In this paper, multi-objective optimization (MOO) of Al2O3-water nanofluid flow in microchannel heat sinks (MCHS) with triangular ribs is performed using Computational Fluid Dynamics (CFD) techniques and Non-dominated Sorting Genetic Algorithms (NSGA II). At first, nanofluid flow is solved numerically in various MCHS with triangular ribs using CFD techniques. Finally, the CFD data will...

Experimental Investigation and Theoretical Model for Subcooled Flow Boiling Pressure Drop in Microchannel Heat Sinks

This study examines the pressure drop characteristics of subcooled two-phase microchannel heat sinks. A new model is proposed, which depicts the subcooled flow as consisting of a homogeneous two-phase flow layer near the heated walls of the microchannel and a second subcooled bulk liquid layer. This model is intended for conditions where subcooled flow boiling persists along the entire microcha...
