  • 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.

    • CD1434: Thermofluidic data-driven modeling

      The CD group at MERL is seeking a highly motivated, qualified individual to join our internship program in the summer of 2020. The ideal candidate will be a senior Ph.D. student specializing in fluid mechanics, control, turbulence modeling, reduced-order modeling, and non-convex optimization. Research experience in computational fluid dynamics (CFD), Lagrangian coherent structures, continuous and discreet adjoint methods is very desirable. Familiarity with computational programming languages like MATLAB, Fortran or C++ (openFOAM level) is expected. Publication of results obtained during the internship is expected. The starting date is flexible between April-June 2020, and the internship will last 3-4 months.
