Experiments on a Shrouded, Parallel Disk System with Rotation and Coolant Throughflow

摘要

The heat transfer and fluid flow characteristics of a cylindrical enclosure having both rotating and stationary walls were investigated in the presence of coolant throughflow. The research was motivated by cooling applications in cavities and enclosures which may be situated adjacent to the rotating shaft in gas turbines, compressors, and similar devices. The local heat transfer coefficients on the rotating disk were found to increase with increasing rotational speed, increasing coolant flow rate, and decreasing spacing. (Author)
