Some characteristics of flow pattern and heat transfer past a circular cylindrical cavity
Abstract
A turbulent vortex in a two or three-dimensional cavity appears to promote an increase in the efficiency of heat transfer. Various cases related to an increase of heat transfer on the basis of the considered phenomenon have been studied. However, there is no report regarding an investigation of the heat transfer from a circular cavity. The present study is, therefore, concerned with the conduction of experiments which were designed to provide information regarding the flow pattern and local heat transfer in the case of such a circular cavity. A single circular cavity in a turbulent boundary layer on a flat plate is considered. Attention is given to the experimental apparatus, the isopleths of Cp on the walls in the cavity, pressure fluctuations in the cavity flow, flow visualization by the oil-film method, local heat transfer characteristics, and two kinds of unstable phenomena in the cavity flow.
