In the process of heat conduction, heat always transfers from _. A. a cold object to a hot object B. a hot object to a cold object C. objects with the same temperature D. objects without temperature difference 相关知识点: 试题来源: 解析 B。解析:在热传导过程中,热量总是从高温物体传递...
解析 B。解析:conduction是热传导,它主要发生在固体中,是通过分子间的碰撞传递热量。convection是热对流,它主要发生在流体(液体和气体)中,是通过流体的流动传递热量。所以主要发生在流体中的是convection,A选项conduction不符合,C选项both错误,D选项neither不对。

PROBLEM TO BE SOLVED: To provide a heat conductive sheet having satisfactory heat conductivity, proper electrical conductivity, and excellent electrostatic removing effects.高木 亮山口 晃生Cattaneo, C., On the conduction of heat, Atti. Sem. Mat. Fis. Univ. Modena, Vol. 3, 3-21, 1948....
Depending on the calculation of the enthalpy change, liquid flow near the steam chamber edge only delivers about 22% of the total energy transferred to the cold oil sands. Ito proposed that the ratio of convection to conduction heat transfer should be in the range of 50% (Ito and Suzuki, ...

Numerical study by conjugate heat transfer is carried out of solar chimney systems for heating and ventilation of dwellings. Conservation equations are solved by finite difference-control volume numerical method. The governing parameters were: the Rayleigh numbers from 5 × 10 8 to 10 11, the Prand...
