Dr. Stephen Tullis, PhD, PEng

My group is doing research in fluid dynamics, both computational fluid dynamics (CFD) and experiments. Complex flows with multiple physical and chemical interactions are of particular interest, so although the applications look very diverse, there are underlying similarities in modelling and experimental approaches.

Topics of current interest include:

• multiphase metallurgical flows

• nuclear thermalhydraulics

• blade hydrodynamics particularly in sports applications (rowing, sailing, sprint canoe/kayak)

• wind turbines, particularly vertical axis turbines

• fluid structure interaction

• DNS, LES and RANS modeling of particulate flow

Previous work includes:

•  DNS and LES of turbulent premixed combustion

•  turbulent boundary layer drag reduction

More details are available in the research pages.

 I teach two undergraduate courses: Mech 4U3 Compressible Flow & Turbomachinery (Fall) and Mech 4AA3 Aerodynamics (Winter) and supervise 2-3 Mech 4M6 Capstone projects . I also teach a graduate course on turbulence and turbulence modelling during the Winter Term. See courses for details and links.

Current Opportunities:

MSc or PhD positions in unsteady hydrodynamics for sports applications. Experience with competitive sport (rowing, canoe, sailing) is a definite asset, besides a mechanical / fluid mechanics background

MSc and PhD positions in modelling of multiphase flows in steelmaking.
