This is a model of a stratified storage tank for thermal energy
storage.
See the Buildings.Fluid.Storage.UsersGuide
for more information.
Limitations
The model requires at least 4 fluid segments. Hence, set
nSeg
to 4 or higher.

Copied model from Buildings and update the model accordingly. This
is for #314.
- June 1, 2018, by Michael Wetter:
Refactored model to allow a fluid port in the tank that do not have
the enhanced stratification model.
This is for issue
1182.
- March 29, 2012 by Wangda Zuo:
Revised the implementation to reduce the temperature
overshoot.
- June 23, 2010 by Michael Wetter and Wangda Zuo:
Changed model that is used to correct the numerical diffusion. The
previous version used the model from Stefan Wischhusen,
An Enhanced Discretization Method for Storage Tank Models within
Energy Systems, Modelica Conference, Vienna, Austria,
September 2006. However, for situations where there is a strong
stratification, this model can lead to a large overshoot in tank
temperatures, leading to a violation of the second law. In this
revision, the model that computes the volume outlet temperatures
has been changed to a third order upwind scheme, which is
implemented in
Buildings.Fluid.Storage.BaseClasses.ThirdOrderStratifier.
- October 23, 2008 by Michael Wetter:
First implementation.
