概要
- 論文の詳細を見る
The pump has vanes which are inclined at an angle with the radius. Experiments were carried out on the performance in each of the combinations of eleven angles of vane from 45° to 135° with four flow channels. The authors also observed the inner flow by means of a high speed camera and a few kinds of probes which contained a new type pitot tube. Their conclusions are as follows : (1) The pump performances are influenced by the vane angle and the sectional area of flow channel. (2) The ratio of the shut-off heat to the head at the maximum efficiency and the maximum power decrease with the increase of the vane angle. (3) There is a regular flow circulating through the flow channel and between the vanes, and the flow pattern depends upon the vane angle.
