Abstract

Recirculation and low-pressure regions associated to flow over bluff bodies such as circular cylinder have resulted in form drag dominance. Splitter plates attachment to cylinder has been found as a promising passive control technique to mitigate such effects. This study aims to examine the implications of splitter plates on the thermal aspects of the flow over a heated cylinder in cross flow, exploring experimentally the effects of wake splitter on the heat transfer coefficients. The experiment was carried out in the wind tunnel for three different Reynolds numbers around 7850, 13650, and 17500. The findings indicated that while the heat transfer performance improves with increasing Re, the addition of splitter plates has augmented the heat transfer coefficients by up to 34%, 77% and 153% for the respective geometry with rear plate, front plate and double plates incorporated to the circular cylinder. The results were explained from the perspective of boundary layer theory. Future work may investigate the local heat transfer coefficient variation with the azimuthal angle of the circular cylinder in cross flow.
