Information

1. Purpose of model

This is a simple model of a heat exchanger with one real gas and one VLE fluid.

2. Level of detail, physical effects considered, and physical insight

The detailed heat transfer is not modeled, only an end temperature for one medium is given by a parameter. There are no heat losses, no limitations for heat transfer and no changes in composition of both media. The model only works in the design flow direction.

3. Limits of validity

This model is only valid for one real gas and one fluid and if the changes of the temperature at the outlet with constant temperature are very small. The plausibility of the temperatures has to be checked (see 7.).

4. Interfaces

gasPortIn: Inlet of the real gas

gasPortOut: Outlet of the real gas

fluidPortIn: Inlet of the VLE fluid

fluidPortOut: Outlet of the VLE fluid

5. Nomenclature

: Heat flow transfered from medium2 to medium1

6. Governing Equations

Energy balances:

7. Remarks for Usage

The plausability of the temperatures at inlet and outlet of the media has to be checked. They have to fit to the chosen type of heat exchanger (e.g. concurrent or countercurrent).
