An Examination of the Flow through Low Pressure Stage of Steam Turbines

概要

論文の詳細を見る
In the low pressure parts of a steam turbine, the annular flow areas are made diverging towards the downstream. In such a case, the fluid behaves with the radial velocity which cannot be neglected in calculation. Presented at the beginning of this paper are a method of calculating the velocity distribution through such stages and also descriptions of some examples of application for the concrete flow pattern. Then are described some results of the measurement of the flow through the last stage of the actual turbine, which show good agreement with theoretical prediction.
