The aim of this work is to investigate the conjugate heat transfer in periodic mounted obstacles channel with oblique plates as vortex generators installed at the rear obstacles on the opposite wall. Special attention will be paid to the analysis of flow evolution and heat transfer enhancement in the intermediate and low Reynolds number range without recourse to turbulent flow. Various physical arrangements are considered as plate length, tilt angle and Reynolds number in order to investigate their influence on the thermal and flow characteristics in the steady state as well as in the self-sustained oscillatory flow.
