ABSTRACT
Overheating of components and devices in electronic systems led to the application of mini and microchannel technologies. The aim is to eliminate as fast as possible the maximum heat quantity from these systems in order to ensure an increased reliability and functional stability. Analysis of a laminar flow through a mini-channel has been done by a numerical model method by considering the surface irregularities. The process has been carried out as three phases and comparison is made on the variation of temperature on different cross-section. The objective of the work is to investigate fluid flow and temperature variation of regular cross-section with that of irregular cross-section. The result for the channel with surface irregularities is compared with those of a smooth channel with regular cross section shape and geometry. From the investigation, we obtain that the actual prediction of flow and heat transfer characteristics of channels of small cross-section requires the considerations of surface irregularities while performing the numerical computations.
