HEAT TRANSFER ON TWO HEATED NEARBY CIRCULAR CYLINDERS

초록

Heat transfer on two nearby circular cylinders of equal diameter immersed in the uniform crossflow at Re=120 and Pr=0.7 was numerically studied. We consider all possible arrangements of the two cylinders in terms of the distance between the two cylinders and the inclination angle with respect to the direction of the main flow. It turns out that significant changes in the characteristics of heat transfer are noticed depending on how they are positioned, resulting in quantitative changes of heat transfer coefficients on both cylinders.
