Defining Physics Analysis Scenes and Plots

Update scenes and plots to display physics values on geometry parts when running the reacting channel simulation.

In reacting channel simulations, it is useful to check the temperature along the length of the reacting channel boundaries to make sure that it is consistent and sufficiently high for the endothermic processes which occur in the reacting channels. You can also monitor the progress of the methane steam reforming reactions by plotting the consumption of reactants and production of products along the length of the reacting channels. It is also important to monitor the temperature and the release of CO2 at the outlet of the firebox.

To display the temperature on the reacting channels:

Open the Temperature scene.

Expand the Scenes > Temperature node and set the following properties:


Node	Property	Setting
Scalar 1	Representation	Volume Mesh
Scalar Field	Function	Temperature
Color Bar	Color Map	thermal

Create another scalar scene to visualise the heat flux that occurs along the boundaries between the reacting channel pipes and the firebox domain.

Create a scalar scene named Heat Flux and set the following properties:


Node	Property	Setting
Scalar 1
Parts	Parts	Regions > Firebox > Boundaries FullFurnace.Pipe1 FullFurnace.Pipe2 FullFurnace.Pipe3 FullFurnace.Pipe4 FullFurnace.Pipe5 FullFurnace.Pipe6
Scalar Field	Function	Boundary Heat Flux
Color Bar	Color Map	gray-darkred

You can also plot the temperature and heat flux within the reacting channels using Reacting Channel X-Y plots.

Right-click the Plots node and select New Plot > Reacting Channel XY Plot.
Create three further Reacting Channel XY Plots and name them:
- Reacting Channel Temperature
- Reacting Channel Heat Flux
- CH4 Mass Fraction
- H2 Mass Fraction

Select the Reacting Channel Temperature node and set the following properties:


Property	Setting
Title	Reacting Channel Temperature
Parts	Regions > Firebox > Boundaries FullFurnace.Pipe1 FullFurnace.Pipe2 FullFurnace.Pipe3 FullFurnace.Pipe4 FullFurnace.Pipe5 FullFurnace.Pipe6

Multi-select all six of the Plots > Reacting Channel Temperature > Data Series > Reacting Channel Co-Simulation: FullFurnace.Pipe# nodes and set Y Variable to Temperature.

Since reacting channels two, four, and six are continuations of reacting channels one, three, and five respectively, you offset the plotting on the x-axis to visualise this continuity.

Multi-select the following nodes for Reacting Channel Temperature and set X Offset to 6.5:
- Data Series > Reacting Channel Co-Simulation: FullFurnace.Pipe2
- Data Series > Reacting Channel Co-Simulation: FullFurnace.Pipe4
- Data Series > Reacting Channel Co-Simulation: FullFurnace.Pipe6

Select the Reacting Channel Heat Flux node and set the following properties:


Property	Setting
Title	Reacting Channel Heat Flux
Parts	Regions > Firebox > Boundaries FullFurnace.Pipe1 FullFurnace.Pipe2 FullFurnace.Pipe3 FullFurnace.Pipe4 FullFurnace.Pipe5 FullFurnace.Pipe6

Multi-select all six of the Plots > Reacting Channel Heat Flux > Data Series > Reacting Channel Co-Simulation: FullFurnace.Pipe# nodes and set Y Variable to Heat Flux.
Multi-select the following nodes for Reacting Channel Heat Flux and set X Offset to 6.5:
- Data Series > Reacting Channel Co-Simulation: FullFurnace.Pipe2
- Data Series > Reacting Channel Co-Simulation: FullFurnace.Pipe4
- Data Series > Reacting Channel Co-Simulation: FullFurnace.Pipe6

To monitor the progress of the methane steam reforming reactions within the reacting channels, plot the mass fractions of one of the reactants (CH4) and one of the products (H2), along the length of the reacting channels:

Select the CH4 Mass Fraction node and set the following properties:


Property	Setting
Title	CH4 Mass Fraction
Parts	Regions > Firebox > Boundaries FullFurnace.Pipe1 FullFurnace.Pipe2 FullFurnace.Pipe3 FullFurnace.Pipe4 FullFurnace.Pipe5 FullFurnace.Pipe6

Multi-select all six of the Plots > CH4 Mass Fraction > Data Series > Reacting Channel Co-Simulation: FullFurnace.Pipe# nodes and set Y Variable to CH4.
To offset the plotting of pipes two, four, and six, multi-select the following nodes for CH4 Mass Fraction and set X Offset to 6.5:
- Data Series > Reacting Channel Co-Simulation: FullFurnace.Pipe2
- Data Series > Reacting Channel Co-Simulation: FullFurnace.Pipe4
- Data Series > Reacting Channel Co-Simulation: FullFurnace.Pipe6

Select the H2 Mass Fraction node and set the following properties:


Property	Setting
Title	H2 Mass Fraction
Parts	Regions > Firebox > Boundaries FullFurnace.Pipe1 FullFurnace.Pipe2 FullFurnace.Pipe3 FullFurnace.Pipe4 FullFurnace.Pipe5 FullFurnace.Pipe6

Multi-select all six of the Plots > H2 Mass Fraction > Data Series > Reacting Channel Co-Simulation: FullFurnace.Pipe# nodes and set Y Variable to H2.
To offset the plotting of pipes two, four, and six, multi-select the following nodes for H2 Mass Fraction and set X Offset to 6.5:
- Data Series > Reacting Channel Co-Simulation: FullFurnace.Pipe2
- Data Series > Reacting Channel Co-Simulation: FullFurnace.Pipe4
- Data Series > Reacting Channel Co-Simulation: FullFurnace.Pipe6

Create reports for the firebox that show the mass flow averaged temperature at the outlet and the mass of CO₂ at the outlet.

Right-click the Reports node and select New > Flow / Energy > Mass Flow Averaged.
Rename the Mass Flow Averaged 1 report to Temperature at Outlet.

Select the Temperature at Outlet node and set the following Properties:


Property	Setting
Field Function	Temperature
Parts	Regions > Firebox > Boundaries > FullFurnace.Outlet

Right-click the Reports > Temperature at Outlet node and select Create Monitor and Plot from Report.
Right-click the Reports node and select New > Flow / Energy > Mass Flow Averaged.
Rename the Mass Flow Averaged 1 report to Mass Fraction of CO2 at Outlet.

Select the Mass Fraction of CO2 at Outlet node and set the following Properties:


Property	Setting
Field Function	Mass Fraction > Mass Fraction of CO2
Parts	Regions > Firebox > Boundaries > FullFurnace.Outlet

Right-click the Reports > Mass Fraction of CO2 at Outlet node and select Create Monitor and Plot from Report.
