This project deals with experimental study of heat transfer and flow characteristics of air flowing through the trapezoidal vortex generator. An experimental work has been conducted to explore the influence of the combined V-rib and exchanger channel having a constant heat-flux on the top wall. Firstly, the V-shaped ribs were mounted on the plain top-wall with a view to creating multiple vortex flows inside. Passive methods using vortex generators (VGs) to enhance heat transfer have been a concern of researchers in recent decades. This study is intended to investigate the strength of the vortex generated by VGs by trying to reduce the pressure drop in the flow. The present work also takes into account the influence of the vortex intensity on the improvement of heat transfer, which can be indicated by the low value of the synergy angle. Experiments were carried out in the current investigation to validate the results of the numerical simulations in the Reynolds number range of 3102 to 16,132. The study results indicate that the observed heat transfer coefficients from the experimental and simulation results have a similar tendency with relatively small errors. A reduction in pressure drop is observed with the use of perforated concave rectangular winglets (PCRWs) against the no perforated ones although there was a slight decrease in heat transfer improvements.
