%X This paper presented investigates nanofluid heat transfer inside the channel. The considered fluid was a nanofluid consisting of water and aluminum oxide nanoparticles. Nanofluid volume fraction from 0 to 4% and Reynolds numbers from 5 to 700 have been investigated. Numerous numerical results have been obtained, including: velocity profile, temperature, pressure and Nusselt number. Pressure, velocity and temperature contours were also presented and streamlines were drawn at different Reynolds numbers. The geometry of this research, decreases the pressure drop. For example, at a Reynolds number of 200, the fluid temperature increase in the geometry of this paper was %181 higher than that of a simple tube (with similar conditions), and the pressure drop was 19% lower than the pressure drop of a simple tube. Also a stagnation point was formed in the flow, where the highest pressure in the problem occurred at that point.
