Dears,
An existing exchanger of DEU type that is used originally in liquid to liquid heat exchange has been used in another service to recover ammonia from a mixture of ammonia gas and some traces of non-condensables where it will work as reboiler and phase change will take place in both shell & tube sides.
I am trying to simulate the case for the new application and I have provided the required geometry to the simulator to see the thermal performance of the exchanger for the new service. However, I want to study the impact of liquid level on the heat transfer as the U-tube will be partly or fully submerged. My question is where can I do the level change in Aspen EDR or in HTRI so that it show me the heat exchanged as a function of portion of Tubes that is submerged.
Please see the sketch of the problem
