An agentic AI workflow connects geometry modeling, three-dimensional meshing, mesh-quality checks, OpenFOAM setup, solver execution, and postprocessing for selectable damper orifices. Steady laminar simulations vary hole diameter, flow rate, and taper orientation. The abstract reports distinct effects on overall pressure drop and local minimum pressure, motivating their separate assessment in designs intended to suppress cavitation.
This study evaluates the NASA CC3 centrifugal compressor when ammonia replaces air without a geometry change. Steady compressible RANS simulations in Ansys CFX use the SST k–ω model. Operating conditions are matched using tip Mach number and flow coefficient, with the air performance curve checked against experiments. Pressure ratio, efficiency, work coefficient, shocks, separation, and tip leakage are compared to examine similarity conditions and their limitations.
