Laminar confined impinging slot jets with nanofluids on heated surfaces

In this paper a numerical investigation is carried out on confined impinging slot-jets with nanofluids on a horizontal heated surface at uniform temperature. The cooling fluid is a nanofluid water/Al2O3 and it is assumed with constant thermo-physical proprieties. The single-phase model is employed and the flow regime is laminar. Different values of the channel height and diameter of nanoparticles are investigated. Results show the increase of Nusselt number together with pumping power.
