Heat Transfer & Thermodynamics engineering - Convective heat transfer coefficient for air Seems a tad high. Most textbooks put it between 0.2 and 4 BTU/hr-ft^2- F http:// www.tufts. edu/as/tam pl/en43/le cture_note s/ch5.html However, your mileage may vary, so you can, and should, calculate it for your specific scenario: http://en.wikipedia.or
Coefficient de convection thermique — Wikipédia Le coefficient de convection thermique ou coefficient de transfert par convection est un coefficient de transfert thermique. Il permet de quantifier un transfert de chaleur réalisé par un phénomène de convection au sein d'un fluide en mouvement (contre un
Convection — Wikipédia La convection est un mode de transfert qui implique un déplacement de matière dans le milieu, par opposition à la conduction thermique ou à la diffusion de la matière. La matière est advectée (transportée-conduite, mais ces termes sont en fait impropres)
大學物理相關內容討論:熱傳導率及熱傳導係數之差別 黃老師您好. 近日有一問題困擾著我. 即是熱傳導率=某一溫度梯度下單位時間內流經 厚度為S 面積為A 之物體的熱量. 單位為W/m.K. 而熱傳導係數之定義為何.
