Saleh Nabi

  • Biography

    Saleh's research interests are analytical, numerical and similitude experimental modeling of fluid flow and heat transfer in complex systems. In particular, his ambition is to derive physically reduced order models for turbulent buoyancy-driven flows in confined regions to reduce the simulation run time by several orders of magnitude.  Prior to joining MERL, Saleh worked on the influence of nanoparticles and the induced micro-convection on heat transfer properties of the base fluid. His doctoral research mainly focused on environmental and architectural fluid mechanics applied to airflow modeling within the built environment with applications of novel and advanced HVAC systems.

    • DA1841: High-fidelity CFD for simulation and optimization

      The Data Analytics Group at MERL is seeking a highly motivated, qualified individual to join our internship program in the summer of 2022. The ideal candidate will be a Ph.D. student specializing in fluid dynamics, with solid background in turbulence modeling and computational fluid dynamics (CFD). Research exposure to one of the following is very desirable but not necessary: PDE-constrained optimization, model reduction techniques, and Physics-informed Neural Nets (PINNs). Ideal candidate is familiar with open-source CFD solvers such as OpenFOAM or SU2. Publication of results obtained during the internship is expected. The starting date is flexible and the internship will last about 12 weeks.
