Abstract
A study on forced convective heat transfer from a rotating drum with fin array to air is performed to improve the heat removal performance from the ECB retarder. Based on a hypothesis that the heat transfer mechanism consists of the cavity flow over the fin tops and the channel flow passing through the fins, the data obtained in the previous report for the rectangular channel flow, which was made by closing the top side of the channel with aluminum tape, are correlated with taking the similarity with the 'usual' channel flow ito account. Finally a semi-empirical equation of the rectangular channel flow for this system is proposed.
