Specifying Fluid component

When species composition information is passed from GT-SUITE to Simerics-MP+ or vice versa, the GT-SUITE species need to be mapped to the corresponding CFD species. In this tutorial, the GT-SUITE species, diesel-vap and n2-vap, defined under FluidGas must be mapped to the respective CFD species. The mapping is done by creating three reference objects CFDSpecies, CFDDefinedSpeciesMap and CFDSpeciesMap using the following steps.

1. The reference object diesel_vap and n2_vap are created under CFDSpecies is defined using the option Same as Unique GT > CFD CFDSpecies Source as shown in Figure 10.93. The Same as Unique GT > CFD CFDSpecies Source allows the mapping of only one GT species to its corresponding CFD species.

Note: Using the Same as Unique GT > CFD CFDSpecies Source option, multiple GT species cannot be mapped to the same CFD species.

2. An object Map is created under CFDDefinedSpeciesMap to create a one-to-one mapping of all fluids from the 1D to the 3D simulation shown in Figure 10.94. The components diesel-vap and n2-vap from GT-SUITE are mapped to CFD as diesel_vap and n2_vap respectively.

3. An object is created under CFDSpeciesMap as shown in Figure 10.95. This serves as the component connection for the coupled CFD simulation. The Map object created under CFDDefinedSpeciesMap is selected as the Object Value for the CFDSpeciesMap object. The CFD components diesel_vap and n2_vap are passed to Simerics-MP+.
