Job Responsibilities

  • Improve and maintain the existing two-phase numerical solver
  • Implement new, and update existing two-phase heat transfer and friction correlations
  • Add new refrigerant fluids; and continuously work to improve the speed of refrigerant fluid property evaluations
  • Work to implement new, and maintain existing 1D and 0D numerical models for components used in air-conditioning and refrigeration systems (condensers, evaporators, TXV valves, compressors, accumulators, etc.)
  • Develop different levels of fidelity to balance speed and accuracy for different applications (e.g. controls vs detailed physics)
  • Keep up with industry trends and new technologies by attending suitable conferences, and building a professional network

Education, Experience, and Skills

Any combination of education and experience that would likely provide the required knowledge and abilities is qualifying. A typical way to obtain the knowledge and abilities would be:

  • PhD degree in Mechanical Engineering (or similar) with a focus on numerical modeling of two-phase fluid flow and heat transfer
  • Proficiency in at least one of the following three languages: FORTRAN, C, C++
  • Experience with either developing from scratch or maintaining a numerical flow solver for two-phase fluid flow with heat transfer
  • Strong fundamental understanding of the physics governing two-phase fluid flow (condensation, evaporation, boiling, etc.)
  • Proficiency in numerical methods for scientific computing

Desired Qualifications

  • Finite volume methods
  • REFPROP
  • SIMPLE algorithm for fluid flow
  • Homogeneous model for two-phase flow
  • Separated (or two-fluid) model for two-phase flow
  • Modeling of Refrigerant plus lubricating oil mixtures
