Abstract

<p>There is problems that an electrical rotating machine loses it’s the output and driving efficiency due to overheating during rotating. Therefore, the improvement of heat removal capacity needs to know the internal flow and heat transfer characteristics. The internal structure of the rotating machine has coaxial cylinders consisting of the inner cylinder and outer cylinder. This study produced three shapes of the rotating coaxial cylinders. By performing a visualization using Kalliroscope flakes, the effect of the shape variation on flow characteristics was investigated.</p>
