CFD Simulation of an Orbiting Scroll Bearing Hub

There are major areas that need to be considered to create a chamber model of a scroll compressor, including the motor and the compression process. Minor energy losses need to be modeled as well, such as bearing losses, line losses, heat losses, and windage losses. One of these windage losses is the orbiting scroll bearing hub that orbits inside the scroll compressor housing. Computational fluid dynamics (CFD) simulations with oil and refrigerant will be modeled as an isothermal multiphase analysis to determine the power of the orbiting scroll bearing hub. These CFD simulations will investigate different dynamic viscosities at multiple speeds. The results of these CFD simulations will also be used to see if the oil reaches the thrust surface of the scroll compressor.
