2125 再生サイクルガスタービン起動時の再生器耐久性評価(J18-1 ガスタービンにおける熱流動問題(1),ジョイントセッション,21世紀地球環境革命の機械工学:人・マイクロナノ・エネルギー・環境)
詳細
It is necessary to calculate a transient temperature profile of gas turbine recuperator for estimation of mechanical life. In case of distributed power generation, such estimation is very important because the equipment is usually operated as daily start up/shut down system. In order to calculate the temperature profile of plate-fm heat exchanger, simplified model is considered. Transient temperature profile can be calculated form the influence of both heat transfer form fluid and heat conduction of heat exchanger itself. Such numerical analysis gives to estimate the expected mechanical life of the equipment at initial evaluation and/or improvement effect of operational modification.
