Investigation of Heat Transfer with Injection and Vortex Generator in Microchannel

Given the lack of fossil fuels, the energy issue in the modern world is of particular importance. This is why finding the best solution for saving energy is important.In this paper, heat transfer was investigated in a microchannel and used to increase the heat transfer from the vortex generator connected to the wall, and also the injection of a very small source of hot water has also been used. In this study has been investigated and compared in three different Reynolds numbers (Re=300, 600, 1000) in injection site and as a unsteady state and 2-dimensional.The results obtained show an increase of 30% of Nusselt numbers and also with a decrease in Reynolds number at the input, which increases heat transfer
