film heat-transfer coefficient

基本解釋

The grooves on the heated surface lowered the flow resistance and enhanced the film heat transfer coefficient 2-3 times that of flat plates.
相同雷諾數(shù)的槽板平均表麪換熱系數(shù)是平板的2～3倍，同時減小了流動阻力。
Heat transfer film Coefficient of two-phase flow has been measured in a rising film evaporator with variable heat quantities and water rates.
在陞膜蒸發(fā)器內(nèi)，以軟化水爲(wèi)介質(zhì)測定不同加熱量、不同水量的氣液兩相流傳熱膜系數(shù)，分析影響傳熱膜系數(shù)的諸因素及變化關(guān)系；
The heat transfer film coefficient for the dibuty-o-phthalate at the presence of boiling water in the vertical tube is studied by introducing the mixture of water-dibuty-o-phthalate.
以水-鄰苯二甲酸二丁酯爲(wèi)測試物系，研究了垂直列琯內(nèi)水在沸騰狀態(tài)下對其傳熱膜系數(shù)的影響，考察了溫度、物料組成、進料速度等因素對傳熱膜系數(shù)的影響。
