- Microchannels which are light in weight, smaller in size, handle low amount of coolants and provide higher surface area to volume ratio give higher heat transfer coefficients are efficient cooling devices for various modern electronic systems where higher heat fluxes are encountered. In this connection an experimental investigation has been carried out on the laminar flow and convective heat transfer of deionized water in circular microchannels. To explore the the validity of classical correlations of friction factor based on conventional sized channels for predicting the fluid behavior of single phase liquid flow of water through circular microchannels experiments were conducted with deionized water with Reynolds number ranging from 71 to 1495. The copper microchannels used in the experiment have the hydraulic diameter of 279 μm and 45 mm length. Pressure drop and flow rates were measured to analyze the flow characteristics. The results show good agreement between the classical correlations of friction factor and the experimentally measured data.
