Abstract: This numerical study investigates the effect of using phase change material slurries (PCMs) on the hydraulic performance of microchannel. The phase change material slurries composed of Dodecanoic acid (PCM nanoparticles) in water (carrier fluid) which is introduced into a rectangular microchannel of 100m height and 10mm length, where bottom wall face a constant heat flux. Energy, momentum and mass equations are solved simultaneously using a carrier fluid with effective temperature dependent physical properties. Under specific conditions including mass flow rate of 1x10-4 kg/s, heat flux of 0.7MW/m2 and PCM nano-particles volume concentration (0-25%), results showed a remarkable increase in the effectiveness ratio, pressure drop, pumping power and entropy generation. Effectiveness index is used to measure the effectiveness of PCM slurries.
