The computational analysis for Microchannel flow in branched network was investigated three dimensional CFD approach. The effect of the change of Inlet Plenum size at constant Aspect Ratio (AR) of the outermost channel on heat transfer in fractal branched micro channel was performed. The properties are cosidred along a particular path along the bifurcated path has considerably effected by Inlet plenum size. Velocity in the inner channel after straight run have reduced significantly even for same AR and Reynolds Number (Re). This leads to the conclusion that IP size effects the velocity after the bifurcation. Due to this effect of inlet plenum size flow patterns change along the flow path which leads to significant change in convective coefficient h and ultimately Nusselts number. Average Nusselts number also observed more that already peported results in the research.
