对流传热(heattransferbyconvection) 组成流体的物质微粒以集团的形式从能量高的热端移动到能量低的冷端而形成的传热。其中由于温度不同而产生密度的差异,在重力场中形成的对流传热为自然对流传热,如在外力的作用下形成物质的流动产生的传热称为受迫对流传递。
Where k is the thermal conductivity of the fluid and Lc is the characteristic length.The physical significance means the heat transfer ratio of convection to conduction.For Nu=1, the heat transfer is pure conduction. Fluid flows Heat transfer between moving fluid andsolid surface or between moving...
1、Convection As mentioned earlier, there are three mechanisms of heat transfer: conduction, convection, and radiation. Conduction and convection are similar in that both mechanisms require material medium, but the difference is that convection requires the presence of fluid motion. And heat transfer ...
