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%.
数值计算结果表明：在相同的形状比和瑞利数下，与达西流传热系数的差别最大可达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.
结果表明，封闭式纵向翅片管的散热量、金属热强度以及自然对流换热系数都要高于开放式翅片管。
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.
结果表明：与空槽道表面换热相比，实验段充满烧结多孔介质后，水流过实验段的平均对流换热系数可提高7～9倍，空气可提高3～30倍；
