Buffer setFlow1

Created Mittwoch 07 Juni 2017

A stationary model of a flow buffer setting an outflowing mass flow.

1. Purpose of Model


The model is supposed to be used for the simplified simulation of static cases. The Buffer_setFlow model can be used to prescribe the mass flow rate in a system.

2. Level of Detail, Physical Effects Considered and Physical Insight


2.1 Level of Detail


Referring to Brunnemann et al. [1], this model refers to the level of detail L1 because the model only computes a set of parameters stationary in time for the given conditions.

2.2 Physical Effects Considered



3. Limits of Validity


The model is only able to calculate stationary situations.

4. Interfaces


4.1 Steam Signals


For details see SteamSignal_blue, SteamSignal_red and SteamSignal_green.

Inlet: Green connector
Outlet: Green connector

4.2 Medium Models


VLE medium model

5. Nomenclature


6. Governing Equations


The model calulates the mass flow differences for reporting.

6.1 Governing Model Equations


The mass flow difference is calculated according to the mass flow rates given at the boundary and the user prescribed mass flow rate.

Summary

A summary is available including the following:

7. Remarks for Usage


The model can only be connected with components with matching connector colour (see Example of Usage in StaticCycles).
To be used to prescribe the mass flow rate in a system.
