摘要：
The overall and local heat-transfer characteristics on the circular cylinder set near a plane surface at the subcritical Reynolds number range (Re=4×104) have been clarified by changing the turbulent boundary layer thickness (δ/d = 0.4 to approximately 1.5) and the clearance (C/d < 1.0), where C is the distance between the circular cylinder and flat plate and d is the cylinder diameter. At C/d < 0.3, where the vortex shedding from the circular cylinder ceases, the flow structure close to the cylinder surface is proposed on the basis of the detailed flow measurements, and the local heat-transfer characteristics have been explained by this flow structure.
