Heat Transfer Library

The Heat Transfer Library is an example Model Library provided with AVEVA Process Simulation. It includes specialized models that you can use to create complex heat exchanger geometries and perform rigorous analysis of the heat transfer and temperature profiles. We subdivide the heat exchanger into cells in which the shell flow and tube flow are in a single direction. This results in a system of interconnected but non-overlapping modules with individual flow arrangements. See the Model Help for the Heat Transfer Library for more information.
This Model Library shares the flow port with the Process Library. This allows you to connect models from the Process Library, such as the Source or Valve, directly to the heat exchanger elements.
Because this Model Library is an example Model Library, you must first import it into AVEVA Process Simulation to use its models in your simulations. You can import this Model Library from the %userprofile%\My Libraries\Examples folder.
The following table lists the models that are available in this Model Library. The table includes very brief descriptions for each model. The Model Help in the AVEVA Process Simulation user interface contains more detailed information for these models. See Open the Model Help for a Model Type or Model Library for more information.

Name |
Type |
Description |
|---|---|---|
|
HU_homogenous* |
Submodel |
Calculates the volumetric fluid properties by assuming a homogeneous mixture of vapor and liquid. |
|
HXCell |
Model |
Represents a heat transfer cell, as described in Section C.3.1 of the VDI Heat Transfer atlas. See the Model Help for detailed descriptions and examples on how to use this model. |
|
RigHXDP_Const |
Submodel |
Provides a simple pressure drop relation for the cell. |
|
RigHXDP_VDI |
Submodel |
Estimates the pressure drop in tubes for a single phase flow according to the VDI Heat Atlas, 6th edition. |
|
RigHXDummySide* |
Submodel |
Calculates the heat and material balance for one side of the cell. You can use this submodel for either the tube side or shell side. |
|
RigHXHTC_Const |
Submodel |
Provides a fixed film heat transfer coefficient that is independent of flowrate and fluid properties. |
|
RigHXHTC_Generic |
Submodel |
Calculates the film heat transfer coefficient as a generic function of the Nusselt number, which in turn is calculated from the Prandtl and Reynolds numbers. |
|
RigHXSide* |
Submodel |
Calculates the heat and material balance for one side of the cell. You can use this submodel for either the tube side or shell side. |
|
RigHXWall* |
Submodel |
Calculates the heat loss through the wall of the heat exchanger. |
* Only Model Writers can view these submodels.
