Created Mittwoch 04 Januar 2017
This version was released July 2017

New Features

General Improvements

Numerical improvement of several components with respect to zero flow conditions
Heat transfer correllations for furnace components adapted to back-flow conditions
compliant with Dymola2018

Components

Heat Exchangers

added HEXvle2vle_1ph_BU_simple
added parameter mass_struc to the following models:
- ClaRa.Components.HeatExchangers.HEXvle2vle_L3_2ph_BU_simple
- ClaRa.Components.HeatExchangers.HEXvle2vle_L3_2ph_CH_simple
- ClaRa.Components.HeatExchangers.HEXvle2vle_L3_2ph_CU_simple
- ClaRa.Components.HeatExchangers.HEXvle2gas_L3_1ph_BU_simple

Mechanical Separation

ClaRa.Components.MechanicalSeparation.Drum_L3_advanced
- m_flow_nom propagated
- included optional heat losses and insulation to drum model
- propagated mass_struc for additional mass of the drum's internals
- added mass of cylinder's top and bottom wall -> dynamic behaviour may slightly change
ClaRa.Components.MechanicalSeparation.FeedWaterTank_L3_advanced
- propagated wall initialisation to top level
- included optional heat losses and insulation
- propagated mass_struc for additional mass of the feedwater tank's internals
- added mass of cylinder's top and bottom wall -> dynamic behaviour may slightly change
ClaRa.Components.MechanicalSeparation.FeedWaterTank_L3
- propagated wall initialisation to top level
- included optional heat losses and insulation
- propagated mass_struc for additional mass of the feedwater tank's internals
- added mass of cylinder's top and bottom wall -> dynamic behaviour may slightly change

Pipes

ClaRa.Basics.ControlVolumes.FluidVolumes.VolumeVLE_L4_Advanced
- number of fluid objects reduced, the density of the momentum cell is now the averaged density in the neighboring energy cells
- the derivatives with respect to time of the potential and the kinetic energy are removed from the energy balance. These variables are usually very small, however the calculation effort is large.
- annotations Modelica language complient
- introduced m_flow_start for initialisation

ClaRa.Basics.ControlVolumes.FluidVolumes.VolumeVLE_L4
- numerical improvements
- Species balance introduced -> model works with media mixes (more than one component)
- annotations Modelica language compliant

Heat Transfer

set type of parameter cf_fouling of furnace ht models to input

-> cf_fouling variable with time
-> can be tuned by controllers if measurements are available

Solid Component

mass_struct is introduced as additional mass to wall components ThickWall_L4, the additional mass is evenly distributed to each shell

Furnace

delay for numerical robustness is now available at expert settings

Utilities

ClaRa.Components.Utilities.Blocks.LimPID guess values (start=0) for resetValueP and resetValueID are set
ClaRa.Components.Utilities.Blocks.FirstOrderClaRa initial equation y_aux=0 added for init option 4 "noInit"

StaticCycle Components

added parameter for consideration of subcooling in preheaters the following preheater models:

ClaRa.StaticCycles.HeatExchanger.Preheater1
ClaRa.StaticCycles.HeatExchanger.Preheater2

new pump models added for connection combinations yelow/blue and blue/blue

ClaRa.StaticCycles.Machines.Pump2
ClaRa.StaticCycles.Machines.Pump3

wall temperature calculation in static flame room models
added summary to each of the components
- HeatExchangers
- ValveConnects
- Machines
- Fittings
- Storage
- Furnace

Bugs

General

removed expandability of eye_int connector (now array with size one) to avoid warnings in Dymola2018

Components

Bugfixed ClaRa.Components.Sensors.SensorVLE_L3_T

Control Volumes

Species balances in ClaRa.Components.VolumesValvesFittings.Pipes.PipeFlowGas_L4_Simple corrected for backflow conditions
ClaRa.Basics.ControlVolumes.FluidVolumes.VolumeVLEGas_L3 fixed bug in summary for showExpertSummary==true
ClaRa.Basics.ControlVolumes.GasVolumes.VolumeGas_L4 updated comments and annotations to be Modelica compliant
ClaRa.Basics.ControlVolumes.GasVolumes.VolumeGas_L4 bugfix in component mass balance at back flow conditions

StaCy

added mechanical connectors for ClaRa.StaticCycles.Machines.Turbine_mech
models ClaRa.StaticCycles.ValvesConnects.Tube1

ClaRa.StaticCycles.ValvesConnects.Tube2
ClaRa.StaticCycles.Furnace.FlameRoom1
ClaRa.StaticCycles.Furnace.FlameRoom2
ClaRa.StaticCycles.Furnace.FlameRoom3
ClaRa.StaticCycles.Furnace.FlameRoom4

can now access functions ClaRa.Basics.Functions.pressureInterpolation and ClaRa.Basics.Functions.vectorInterpolation

added ClaRa.Initialisation.Combustion.InitialiseCombustionGas which is used in

ClaRa.StaticCycles.Furnace.Burner1
ClaRa.StaticCycles.Furnace.Burner2

check if concept of update.bat is still needed. It was reported that update.bat did not work on 64 bit systems @R122
