中文摘要 | 本文回顧近年來對沸騰系統熱傳穩定性之研究發展。本研究探討池式及流動沸騰系統之穩定區域(stable)、虛擬穩定區域(metastable)及不穩定區域(unstable),利用等面積法則(equal area cut)可定義系統之中性穩定區域(neutrally stable)【核沸騰和膜沸騰可穩定共存】。低於此熱通量時核沸騰狀態較膜沸騰為穩定,高於此熱通量分佈則膜沸騰狀態更為穩定。核能電廠若在平衡熱通量以下操作則為絕對安全的狀態。 |
英文摘要 | This paper reviewed the recent progress made toward stability characteristics of boiling systems. The boiling regions of stable, metastable, and unstable characteristics were allocated on pool and flow boiling systems. The so-called "neutrally stable" boiling regiom could hence be identified using the "equal-area cut", along which the nucleate and film boiling modes could stably co-exist. Below this specific region the nucleate boiling is relatively more stable than film boling, while above, the reverse was true. Nucleate power plant operated at the stable nucleate boiling mode is inherently safe. |
