HEAT TRANSFER FROM ROTATING DISCS WITH FINITE THICKNESS SUBJECTED TO OUTER AIR STREAMS

摘要

The heat transfer from rotating discs in an outer air stream is of major importance for many technical applications. Experimentally determined heat transfer coefficients are presented for a large range of rotational and crossflow Reynolds numbers including also the effects of finite disc thickness and incidence to the uniform air stream. The extreme conditions of a rotating disc in still air and a stationary disc in an air crossflow are considered, too.
