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...

Temperature has a great influence on the normal operation and service life of high-power electronic components. To cope with increasingly severe heat problems in integrated circuits, an enhanced transfer factor E is introduced to evaluate comprehensive performance microchannel sinks (MCHS). The computational fluid dynamics (CFD) software was used numerically study flow characteristics cone-colu...

Cooling of electronic chips has become a critical aspect in the development of electronic devices. Overheating may cause the malfunction or damage of electronics. The time needed for heat removal is particularly important in a wide range of electronic systems, such as switching circuits. Thus, it is important to characterize the transient behavior of the system and determine the response. Most ...
