The generators, coolers, and modular devices criterion comes in both sustainable as well renewability electrical heat sinks. recovery operations are optimized with the help modeling using MATLAB software. material science based applications can be modeled simulink modeling. numerical algorithmic method for...

This paper experimentally and numerically investigated the heat transfer and friction characteristics of microfluidic heat sinks with variously-shaped micro-ribs, i.e., rectangular, triangular and semicircular ribs. The micro-ribs were fabricated on the sidewalls of microfluidic channels by a surface-micromachining micro-electro-mechanical system (MEMS) process and used as turbulators to improv...

The possibility of using an earth heat sink to absorb the waste heat from an underground power plant operating in a closed cycle was investigated. Preliminary calculations based upon a transient heat conduction analysis were carried out to determine the order of magnitude of dimensioas of the required heat sink. The calculations have shown that earth heat sinks may be practical and that they sh...

In this study the performances of various non-circular microchannel heat sinks (normalized with circular shape) have been comparatively analyzed for CuO-water nanofluid and baseline pure water flow. Nusselt number and Poiseuille number for each microchannel and thermo-physical properties of CuO-water nanofluid (viz., thermal conductivity, viscosity, specific heat and density) have been designed...

The changing configurations of continents due to plate tectonics is thought to be responsible for some of the variation in climate over the last 600 Ma. Different topological constraints on the oceans may affect their ability to transport heat poleward and change the equilibrium pole-equator temperature of Earth. An ocean model was run for three simple continental geometries to determine the ef...

The possibility of building a high voltage electrostatic air pump for cooling of microelectronics is investigated. Existing cooling technology no longer provides adequate heat dissipation due to excessive heat generation caused by the growing component density on electronic devices. Heat sink fins are packed more closely to increase the heat exchange surface area, resulting in narrower channels...

Description Background – Given the increasingly stringent cooling demands in mid to high-end electronic packages, there is a need for high cooling power density yet robust cooling solutions. Convective liquid cooling using micro-channel heat sinks in single-or two-phase operation has received a lot of attention in recent research. Whereas single-phase cooling is simpler and more robust, two-pha...
