Nano fluids have great significance towards heat transfer applications. It needs to study the nanofluid flows through channels with heat transfer. A steady an incompressible two dimensional forced convection laminar parallel flow through a microchannel and the effect of impinging plane jet flow in a mini-channel using nanofluids studied numerically. In the present study, nanofluid flows through channels are modeled by using a two-phase approach Eulerian-Eulerian model is used. The present study is valid the Reynolds number up to laminar zone. The governing equations solved by using finite volume schemes with first order implicit for time integration. Studied heat transfer characteristics, the parallel flow through micro-channel Re from 109.54 to 285.6, observed heat transfer enhancement with 17.63%, studied the effect of volume fraction in heat transfer with the parallel flow and also studied the effect of base fluids that is the kerosene-based fluid has netted more heat transfer than water-based nanofluid. With the jet flow as the Reynolds, number increases average nusselt number also increases, and also observed the effect of volume fractions on the heat transfer at Re = 200, as the volume fraction from(0.001% to 0.1%) there is an enhancement with 223.23%. Studied the effect of aspect ratios on the heat transfer rate, observed that as the jet inlet to a target surface distance increases average nusselt number decreases. From three different nanofluids (H2O−Al2O3, H2O−Cuo, H2O−T iO2 ) at all volume fractions 0.1%, 1%, 2% the H2O−T iO2 has better enhancement in heat transfer. Observed that the velocity and temperature difference between the liquid phase and solid phases is very small and negligible. The present results are matching well with experimental and numerical results available in the literature.
