Dr. Joshua Schlegel has been researching nuclear reactor thermal-hydraulics and two-phase flows for several years. This work has included experimental, analytical and numerical studies such as the development of an objective error-minimization algorithm for benchmarking the interfacial area transport equation, the development of specialized impedance void meters, and the development of models intended to improve the modeling of interfacial drag and interfacial area transport in large diameter channels in advanced thermal-hydraulics analysis codes.

His current research interests include:

  • Advanced instrumentation for two-phase flows
  • Experimental measurement of interfacial are concentration and other two-phase flow parameters
  • Continued development of the interfacial area transport equation
  • Implementation of interfacial area transport in CFD codes
  • Hydrodynamic models for two-phase flows in CFD
  • Advanced light water reactor safety and passive safety systems
  • Thermal-hydraulics and safety analysis of small modular reactors

Keywords: nuclear, thermal-hydraulics, interfacial area, CFD, safety, small modular reactor
