How to change the baffle spacing in HTFS and address the issue of reduced pressure heat transfer coefficient
Thread Content
In HTFS, in design mode, how can parameters such as the spacing of the baffle plates be changed? The heat transfer coefficient in the calculation results is high; what parameters can be changed to reduce it? Also, I increased the pressure of the material in the shell side (the condenser); why then did the heat transfer coefficient decrease? All other parameters remain unchanged; by increasing the pressure, the boiling point rises and the temperature difference increases, so the heat transfer efficiency should be better, right? Confused.

Structural parameters cannot be adjusted in design mode; you can switch to the rating/checking mode to adjust the baffle spacing； 2. Increasing the pressure on the shell side raises the boiling point and increases the temperature difference; the key issue is the extent to which the heat transfer load increases. If the increase in heat transfer due to this factor is less than the increase in the logarithmic mean temperature difference, then, according to Q=K.A.Δt, with the heat transfer area remaining unchanged, the value of K will decrease
