Flow across tube banks

WebThe question then arises as to why flow across tube banks s:loulcl bo so ;:lUch less efficient than flo\" through tubes. The answer is known in a g eneral way . Flow through tubes is entirely frictional; where~s, in flow across tubes, the boundary layer ~rea~s a1ay from the rear surface WebAir flows vertically upward across the tube bank. The flow can be induced by fans above the bundle or forced by fans below the bundle. The heat transfer is countercurrent, because the hot fluid enters at the top of the bundle and flows downward through successive passes.

WebNov 28, 2014 · This phenomenon also exists during flow across tube banks. For large heat exchangers in deep laminar flow, it can result in a decrease in the average heat transfer coefficient by a factor of 2 or more compared with what would have been predicted based on calculations. Therefore Bell proposed to introduce a Webflow over the horizontal tube banks in the shell-side of the CHX unit. To determine the pressure distributions on the shell-side of the CHX unit, numerical simulation using the commercial CFD package, ANSYS CFX 16.2, has been performed in the present study.
