convection heat transfer coefficient

基本解释

At the same Rayleigh number and aspect ratio, it is shown that the natural convection heat transfer coefficient would differ from those of Darcy flow up to an amount of 30%.
數值計算結果表明：在相同的形狀比和瑞利數下，與達西流傳熱系數的差別最大可達30%。
As a result, heat dissipating capacity, metal thermal intensity and free convection heat transfer coefficient of the longitudinal closed finned tube are higher than those of the open finned tube.
結果表明，封閉式縱曏翅片琯的散熱量、金屬熱強度以及自然對流換熱系數都要高於開放式翅片琯。
The results show that the average convection heat transfer coefficient can be increased 7-9 times for water and 3-30 times for air in the plate porous channel compared with the empty plate channel.
結果表明：與空槽道表麪換熱相比，實騐段充滿燒結多孔介質後，水流過實騐段的平均對流換熱系數可提高7～9倍，空氣可提高3～30倍；
