The present study experimentally investigated a new hybrid cooling scheme by combination of a microchannel heat sink with a micro-synthetic jet actuator. The heat sink consisted of a single rectangular microchannel measured 550 μm wide, 500 μm deep and 26 mm long. The synthetic jet actuator with a 100 μm diameter orifice was placed right above the microchannel and 5 mm downstream from the chann...

Shear stress, pressure, and flow rate are fluid dynamic parameters that can lead to changes in the morphology, proliferation, function, survival of many cell types have a determinant impact on tissue function viability. Microfluidic devices promising tools investigate these behaviour within different microchannel geometries. This study discusses analyses designed microfluidic channel geometries...

Increasing the power and reliability of microelectronic components requires heat sinks with greater transport performance. This study investigates hydraulic performance a silicon sink under constant flux 100 W/cm2 liquid coolant running through parallel microchannels. The coupled transfer walls coolant, modelled as single-phase fluid, is examined over Reynolds number range 100?Re?350 for micro-...

In this work, single layered (SL) and double layered (DL) flexible microchannel heat sinks are analyzed. The deformation of the supporting seals is related to the average internal pressure by theory of elasticity. It is found that sufficient cooling can be achieved using SL flexible microchannel heat sinks at lower pressure drop values for softer seals. Double layered flexible microchannel heat...

In this study, high-fidelity conjugate heat transfer simulations are used to model a micro-channel exchanger (MCHE) in crossflow study its thermal-hydraulic performance. Three different microchannel geometries, namely circular, triangular, and square with louver-shaped fins, considered. The local flow field showed strong coupling between the flow, solid domain, crossflow. separation wake region...

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 nanoparticles and diffe...

We propose and demonstrate a new fabrication process of a microchannel using the Damascene process. This process aims to integrate photonic circuits with microchannels fabricated in a glass film. The microchannel is fabricated by the removal of the sacrificial layer after a sacrificial layer is formed by the Damascene process and the cover is formed by sputter deposition. A thin cover layer can...
