Multicomponent Mixing using a Nozzle: Exercise 2—Defining Physics Modules
Physics specifications are handled in Creo Flow Analysis using modules.
1. In the Flow Analysis Tree, right-click Physics and select Select Physical Models or click Physics Module. The Physical Model Selection dialog box opens.
2. Under Available Modules, select Multicomponent Mixing and click
3. Under Available Modules, select Heat and click
4. Click Close to close the Physical Model Selection dialog box.
Specifying Multicomponent Mixing Module Conditions
1. In the Flow Analysis Tree, under Physics right-click Multicomponent Mixing.
2. Click Add component. Do this three times.
3. In the Model tab, under Components the entities comp_1, comp_2, and comp_3 appear.
4. Rename the entities as:
comp_1 to CH4
comp_2 to O2
comp_3 to H2O
