液膜沸騰 的英文怎麼說
中文拼音 [yèmófèiténg]
液膜沸騰
英文
film boiling-
Heat transfer will worsen if structure parameters of the spring inserts are not fit. the paper think that the mechanism of heat transfer enhances of the spring inserts is the laminar flow lining is thinner because of librating of the spring inserts, accordingly the part of convection is enhanced. but the part of boil is not influenced
通過彈簧插入物的各個參數對傳熱性能的影響分析，認為彈簧插入物對豎管降膜蒸發傳熱強化的機理主要是彈簧的振動加強了液膜的湍動，減薄了層流內層，從而強化了對流傳熱分量，但對沸騰傳熱分量沒有影響。Improvement is made on evaporation and concentration technology of saponification waste alkali liquor : exterior heating inner pipe boiling rising membrane evaporator is innovated into an exterior heating boiling forcefully recycling evaporator, and an evaporation assistant is added in the saponification waste alkali liquor
對皂化廢堿液蒸發濃縮技術進行了改進：將外加熱式管內沸騰升膜蒸發器改造為外加熱式管外沸騰強制循環蒸發器，並在皂化廢堿液中添加蒸發助劑。The main results in this paper are as follows : ( 1 ) study on starting up performance of thermosyphon : according to the study on the states before and after starting up of thermosyphon with the various filling amount, it is considered that the phase change heat transfer inside the copper - water thermosyphon with a large ratio of length and diameter is not only influenced by the boiling degree of superheat, but also controlled by evaporation and companied with the boiling of the thin liquid film
本文的主要研究結果為： （ 1 ）熱虹吸管啟動性能的研究：通過對從不同充液量、啟動前狀態、內部汽化核心狀態對啟動的影響所進行的試驗研究，認為大長徑比的銅?水熱虹吸管管內相變不僅僅為沸騰，而是以蒸發為主，伴有薄液膜的沸騰。The results denote that the sand layer can greatly enhance heat transfer in high temperature region because it changes film boiling to liquid film evaporation in the sand layer
在高溫金屬面上覆蓋砂層后，可將高溫面上的膜沸騰轉化為砂粒表面的液膜蒸發，從而大幅度提高表面換熱系數，強化冷卻能力。分享友人
