Problem of using SW6 for calculating excessive non-piping areas in fixed-tube-sheet heat exchangers
Thread Content
There are some unconventional heat exchangers, such as falling film evaporators and full-liquid evaporators, in which the tube bank constitutes only a small portion. When using SW6 for calculations, can the value of k be altered by increasing the area of the baffle grooves, so that conventional calculation methods can be applied? If so, how should this issue be addressed for heat exchangers with a single flow path and no baffles?
Some piping configurations may not fall within the calculation model for 151 plate gaskets, and this should be taken into account. If we set this question aside. So actually, as long as the values are adjusted to make it fit, that’s fine. The area of the partition slots and the spacing between the tubes all play a role
