SprayAttemporator

Created Freitag 09 Juni 2017

A stationary model of an spray attemporator assuming a fixed outlet temperature.

1. Purpose of Model


The model is supposed to be used for the simplified simulation of static cases. Its main purpose is to provide appropriate start or nominal values for similar dynamic model versions.

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 Fundamentals:SteamSignal green

inlet: Green connector
outlet_1: Green connector
outlet_2: Red connector

4.2 Medium Models


VLE medium model

5. Nomenclature


6. Governing Equations


6.1 Governing Model Equations



Energy


The outlet 1 enthalpy is calculated from the fixed outlet temperature

The inlet 2 mass flow, which is the required mass flow at the inlet 2 enthalpy to reach the set outlet temperature T, is calculated with the stationary energy balance

Pressure


The fluid pressure is assumed to be constant

Mass


The stationary mass balance is given by

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).
