When I studied the application* Concentric tube heat exchanger(Application Library path: Heat_Transfer_Module/Applications/concentric_tube_heat_exchanger, version: 5.4), I found a variable *ht.DeltaH in the expression of E (effectiveness of heat exchanger), which I couldn't find it in the Help document. What is the meaning of the variable ht.DeltaH ? Thanks for your help!

Hi,

If you search for ht.DeltaH using the Find tool (press Crtrl+F), you will see that where it's defined, and moving to that list of variables in an Equation View node (enable Equation View in the Show More Options dialog box), you can see its definition and that it's the sensible enthalpy, which is related to sensible heat. We will look into if we can make the model documentation more clear about the variables that it uses.

Best regards,
