In order to overcome the difficulty mentioned above, this paper provides an improved heat transfer equation and a mended bem for the problems. first of all, the enthalpy and the " virtual temperature " are introduced into the paper to eliminate several mutative thermophysical properties in the heat transfer equation. secondly, the movement of the boundary between the solid and liquid phases in the billet is educed by virtue of the laplace transform
這些改進包括:引入熱焓和「虛擬溫度」的概念,對非常數的熱物性參數進行整合:充分考慮鑄坯凝固潛熱釋放帶來的影響,利用「溫度回升法」來加以處理;利用拉氏變換和反拉氏變換的原理來對凝固過程中鑄坯內部固液相界面的移動方程進行了推導和求解,在凝固過程中充分考慮鑄坯內部的固液兩相的影響等等。Adiabatic throttling process of gas is not isoenthalpic
氣體的絕熱節流過程不是等焓過程Abstract : on the basis of the principle of equivalent enthalpy drop, the online calculating model on the influence of every heater end temperature difference on the unit economy is established which shows the online influence degree. therefore, it provides the theory basis for overhaul workers
文摘:以等效焓降理論為基礎,建立了各級加熱器端差對機組經濟性影響的在線計算模型.通過該計算模型可以在線顯示每級加熱器端差對機組熱經濟性影響的程度,從而為運行檢修人員提供了理論依據,對電廠節能有一定的現實意義
