Defining Reactions

Within the Models node, select the Eddy Break-up node.

Change the Reaction Control property to Standard EBU.

Open the Reacting node.

Right-click the Reactions node and select New Reaction.

A new node named Reaction 1 will appear under the Reactions node. Three more nodes, named Reactants, Products and Properties, will also be displayed under the Reaction 1 node. Begin by defining the first reaction:

Right-click the Reactants node and select Add Reactant > C3H8.

A node named C3H8 will appear underneath the Reactants node.

Right-click the Reactants node again and select Add Reactant > O2

A node named O2 will appear.

Now add CO and H₂ as products by right-clicking the Products node and selecting Add Product...

Once this is complete, this section of the simulation tree should appear as shown below.

With all the necessary species added to Reaction 1, the reaction stoichiometry must now be specified.

Select the C3H8 node and, in the Properties window, enter 1.0 for the Stoich. Coeff.

Repeat this for O₂, CO and H₂, assigning stoichiometric coefficients of 1.5, 3.0 and 4.0, respectively.

The specification of Reaction 1 is now complete.

Follow the same procedure to define the remaining two reactions of the chemical reaction scheme:

(4)

(5)

Save the simulation.
