Fluid Flow and Heat Transfer around a Cylindrical Protuberance Mounted in a Flat Plate Boundary Layer

摘要

Fuel oil storage tanks are set up all parts of the world for stable energy supply. In a cold district, the oil must be keeping warm. In the plane of the heating system of the tank, it is necessary to estimate the heat loss from the shell and roof of the tank. To make the basic data, experimental studies were carried out on the fluid flow and local heat transfer around a cylindrical protuberance with the height/diameter ratio of 0.35 mounted in a flat plate laminar and turbulent boundary layer. The local drag coefficient and characteristics of the local and average heat transfer around the cylinder are clarified. The results obtained were compared with the ordinary results of a cylinder with the height/diameter ratio of 1.0.
