%X Cross-corrugated triangular channels increase heat transfer in heat exchangers. The mixing effect increases the heat transfer coefficient at the surfaces. In this study, the fluid flow and heat transfer in a triangular corrugated channel are modeled under two constant heat fluxes and different Reynolds numbers. In order to validate, k-ω turbulence model is used. Also, the effect of magnetic field is investigated in different locations of the channel and the channel entrance area is shown as the optimal area for application of the magnetic field both in terms of heat transfer coefficient and friction coefficient. It is also observed that the Nusselt number always increases with Reynolds increase, but the friction coefficient only increases when the magnetic field is positioned at the entrance area of the channel with the Reynolds increase and decreases in other cases. The presented results can be helpful for improving the performance of plate heat exchangers.
