Abstract

In this paper, an experimental study was conducted on double micro–heat exchanger (DMHE) device for laminar heat transfer of the Graphene nanoplatelets (GNP). The heat transfer, pressure drop and pumping power of Graphene nanofluid were measured. The thermal properties (viscosity, density, and thermal conductivity) were measured experimentally in the laboratory at different concentrations (0.02, 0.055 and 0.06% wt.). In addition, the effect of weight fraction and inlet temperature and mass flow rate on logarithmic mean temperature difference and the overall heat transfer coefficient were evaluated in DMHE device. The final results showed that the overall heat transfer coefficient and effectiveness of DMHE device improved by raising the weight fraction of GNP and the overall heat transfer coefficient improved to 51.1% at Reynolds number of 425 and weight concentration of 0.06% wt. The experimental results showed that pressure drop and pumping power were higher for (0.06% wt.) compared to (0.02%wt. and 0.055% wt.).
