摘要：

Fuel oil storage tanks are used in the industrial regions of the world to provide a stable energy supply. In cold regions, the oil must be kept warm. In designing the heating system of an oil storage tank, it is necessary to estimate the heat loss from the shell and roof of the tank. To characterize these heat-loss properties, experimental studies were carried out on the fluid flow and local heat transfer around a cylindrical protuberance with a height/diameter ratio of 0.35 mounted on a flat plate in laminar and turbulent boundary layers. The local drag coefficient and characteristics of the local and average heat transfer around the cylindrical protuberance are clarified. The results obtained were compared with the results of an ordinary finite circular cylinder with the height/diameter ratio of 1.
