Experimental Investigation of Fluid Flow Behaviour in Parallel Microchannel Using Micro-PIV

With the miniaturization of the system, the demand for high heat flux removal technologies increases. Innovative technology is the use of microchannel using water as a coolant which can handle the high rate of heat fluxes. For a given pumping power, the rate of flow through the microchannel is low, therefore, many microchannels operating in parallel are required. In this present work, an experimental study of flow through three rectangular parallel microchannels has been carried out. The experiments are performed using micro-PIV at various flow rates and different concentrations of the seeding particles. The post-processing of raw images captured during the micro-PIV experiment is done by PIV Labs software. The experimental analysis is done for various parameters like the concentration of seeding particles and the effect of flow rates. Experimental results are compared with analytical solutions for the parallel microchannel.
