Seeking expert advice on the condenser issues in EDR simulation! Thank you!
Thread Content
Let’s simulate a condenser now. The warning that appears after running the simulation is as follows: the required fraction of the surface area for cooling the liquid phase is 8% (this is an approximate calculation; it might be conservative, especially if the shellside resistance plays a significant role in the cooling process). However, the number of tubes that are actually submerged, as calculated using a balanced pressure drop model, is 5, which means that only 3% of the surface area is covered by the liquid phase. You can run the simulation again by entering an appropriate value for the fraction of the surface area that is submerged, so that the input value matches the required value. Could some expert help me explain the actual meaning of this warning? Thank you so much! ! :P
What you simulate needs to be only 8% of the area you set; your setting is too conservative.
Hello, could you help me translate the entire content? I’d like to confirm whether my understanding is correct; thank you very much!
The number of immersion tubes is 5, accounting for only 3% of the heat exchange area; you can change the value entered for Area Fraction Submerged to match this requirement.
Hello, I have a question: in the case of gas-side condensation, if there are many tubes submerged, it’s mainly sensible heat that is involved. Isn’t this a poor approach? Regarding the condensation of steam in the shell side, is it true that the less liquid accumulates in the shell side, the better? Please advise. Thank you
Hello, I’ve encountered this issue in simulations recently as well; 8% is required, but currently only 3% is available. Does this mean that the area of the liquid that is under supercooling is smaller, and thus it’s necessary to increase the heat exchange area for the supercooled liquid? Or can 3% immersion of the tubes be sufficient to meet the 8% requirement? I’m not sure what this means – please advise. Thank you
