Abstract

We expanded the continuum momentum and energy equations for laminar forced convection in two-dimensional V-Shaped micro-channels and nano-channels under hydrodynamically and thermally fully developed conditions with the first-order velocity slip and temperature jump boundary conditions at the channel walls. Closed form solutions are obtained for the fluid friction and Nusselt numbers in the slip-flow regime. DI water, Methanol, Nano are use as the working fluid and flow through micro-channels with different hydraulic diameters ranging from 57−267 μm in the experiments we examined the experimental results of flow characteristics & check behavior of the laminar regime when Re = 50−850. The Reynolds number at transition from laminar to turbulent flow is considered. Attention is paid to comparison between predictions of the conventional theory and experimental data, obtained during the last decade, as well as to discussion of possible sources of unexpected effects which were revealed by a number of previous investigations.  Experimental results in heat transfer indicted that forced convection in micro channel heat sink exhibited excellent cooling performance, especially in the phase change regime. It will be applied as heat removal and temperature control devices in high power electronic components. When the critical nucleate heat flux condition appeared, flow mechanism changed into fully developed nucleate boiling and accompanied with wall temperature decreased rapidly and pressure drop increased sharply. Experimental results also indicated that the critical bubble size of methanol was between 54−85 μm.
