After determining the performance, basic geometry, and flow parameters of the centrifugal compressor, we ran the single path impeller CFD to further tune the detailed geometry of the impeller.
In addition, we compared the CFD results with our Impeller Design program to validate the reliability of the CFD.
Compressor Rig CFD
We ran a much complicated and realistic compressor simulation, with components setup from intake, impeller rotation, vaneless diffusion and spiral housing outlet.
This CFD was aimed to validate the reliability of a holistic compressor simulation by comparing the simulation results with the experiment results we gathered during the compressor rig experiment.
Compressor CFD
This CFD simulated the full-stage centrifugal compressor running in the jet engine. Therefore, the simulation components were changed into: intake, impeller rotation, wedge-vane diffuser, radial to axial flow path and guide vanes.
The CFD results of this stage were then used to generate the performance map of the centrifugal compressor stage.
Combustor CFD
This CFD simulation had two main purposes. First, to prove that the pressure loss of the combustion chamber was close to the designed requirement. Second, to get understanding of the complex flow pattern inside the burning chamber.
Thereby, we could arrange the combustion holes more precisely to generate circulation in primary zone and distribute adequate mass flow ratio among different zones in the combustion chamber,
Turbine CFD
For turbine CFD simulation, we ran stator CFD, rotor CFD, stator + rotor CFD, and finally the holistic turbine stage CFD analysis.
The simulation results of stator+rotor CFD were then used to generate the performance map of the turbine stage.
