B135 ガスタービン翼の水ミストを伴うフィルム冷却法に関する基礎研究(OS-4:対流伝熱(3))
詳細
In order to improve the thermal efficiency of a gas turbine, an attempt to operate the gas turbine at higher gas temperature has been made. Although the film cooling of the turbine blade by blowing out the air flow of low temperature along the blade surface is the most effective method, the improvement is approaching in the limit. In the present paper, the introduction of the mist flow was experimentally examined. The present experimental results showed that the maximum cooling efficiency was 24 % under the mist flow.
