Received: 17 March 2018 Accepted: 9 October 2018 In the present work, the effect of the angle of a triangular vortex generator on the heat transfer of a flat plate is investigated. Incompressible three-dimensional fluid flows in a channel with constant temperature boundary condition. The results showed that the Nusselt number increases and the pressure decreases with the Reynolds number. It is demonstrated that the increase in the angle from 30° to 90° has a significant effect on the Nusselt number. The pressure drop remains constant at a 60° angle with increasing Reynolds number. The results revealed that the longitudinal vortices that have an important effect on the heat transfer become stronger at larger angles of the vortex generator.
