Visualizing Coal Combustion Products, Temperature, and Velocity

You visualize the distribution of the mass fraction of CO, CO₂, and SO₂ as well as the temperature in the form of contour plots. The velocity field is displayed as a line integral convolution plot.

To visualize the results:

Create a transform that reflects the coal combustor geometry along the symmetry axis.
1. Right-click the Tools > Transforms node and select New Graphics Transform > Graphics Symmetry Transform.
2. Select the Graphics Symmetry Transform 1 node and set Plane to [0.0, 1.0, 0.0, 0.0].
Create a scalar scene that is reflected along the symmetry axis.
1. Right-click the Scenes node and select New > Scalar.
2. Change to the Scene/Plot tab, select the Outline 1 node and set Transform to Graphics Symmetry Transform 1.
3. Select the Outline 1 > Parts node and set Parts to all region boundaries except AXIS.
4. Select the Scalar 1 node and set Transform to Graphics Symmetry Transform 1.
5. Change to the Simulation tab, right-click the Scenes > Scalar Scene 1 node, then copy and paste it onto the Scenes node. Repeat this step four times to obtain a total of five scalar scenes.

Visualize the mass fraction of CO:

Select the Scenes > Scalar Scene 1 node and rename it as CO.
Select the CO > Scalar 1 node and set the following properties:


Node	Property	Setting
Scalar 1	Contour Style	Smooth Filled
Scalar Field	Function	Mass Fraction of CO

Visualize the mass fraction of CO2:

Select the first copy and rename it as CO2.

Select the CO2 > Scalar 1 node and set the following properties:


Node	Property	Setting
Scalar 1	Contour Style	Smooth Filled
Scalar Field	Function	Mass Fraction of CO2

Visualize the mass fraction of SO2:

Select the second copy and rename it as SO2.

Select the SO2 > Scalar 1 node and set the following properties:


Node	Property	Setting
Scalar 1	Contour Style	Smooth Filled
Scalar Field	Function	Mass Fraction of SO2

Visualize the temperature:

Select the third copy and rename it as Temperature.

Select the Temperature > Scalar 1 node and set the following properties:


Node	Property	Setting
Scalar 1	Contour Style	Smooth Filled
Scalar Field	Function	Temperature

Visualize the tracks of the coal particles:

Select the fourth copy and rename it as Particles: Mass Fraction of Char.
Delete the Particles: Mass Fraction of Char > Scalar 1 node.
Right-click the Particles: Mass Fraction of Char node and select New Displayer > Streamline.

Edit the Streamlines 1 node and set the following properties:


Node	Property	Setting
Streamlines 1	Mode	Tubes
	Transform	Graphics Symmetry Transform 1
Color Bar	Color Map	white-red

Visualize the velocity field:

Create a vector scene and rename it as Velocity.
Select the Outline 1 node and set Transform to Graphics Symmetry Transform 1.
Select the Outline 1 > Parts node and set Parts to all region boundaries except AXIS.
Select the Vector 1 node and set the following properties:


Node	Property	Setting
Vector 1	Display Mode	Line Integral Convolution
Vector 1	Transform	Graphics Symmetry Transform 1
Vector Field	Function	Velocity > Lab Reference Frame (default)

Save the simulation.
