Hongtao Qiao

Hongtao Qiao
  • Biography

    Prior to his PhD, Hongtao worked at Carrier Corporation developing advanced steady-state computer simulations for HVAC systems. During his PhD, he developed a comprehensive transient modeling framework for thermo-fluid systems to explore complex dynamic characteristics of vapor compression cycles. Currently, Hongtao works on the control-oriented multi-physical system modeling.

    • MP1443: Numerical optimization of thermal fluid systems

      MERL is seeking a motivated and qualified individual to conduct research in numerical modeling and optimization of thermal fluid systems. A solid background in numerical simulation of fluid dynamics and heat transfer is required. Skills in numerical optimization in partial differential equations are expected and experiences with OpenFOAM are highly desirable. Senior Ph.D. students in applied mathematics, chemical/mechanical engineering and other related areas are encouraged to apply. The duration of the internship is about 3 months.
