RESEARCH INTERESTS

Professor Habashi’s research group at the McGill CFD Lab have made significant and original strides in the fields of computational aerodynamics (subsonic, transonic and hypersonic flows) and in the simulation of all aspects of in-flight icing (aircraft, rotorcraft, jet engines). They continue to address in a multi-physics manner important issues in these fields, by developing new mathematical models that can be incorporated into computational codes usable by practitioners. The CFD Lab maintains a very strong interaction with industry and academia, worldwide, to the benefit of all sides, with graduate students well prepared for a career industry or academia.

RESEARCH FUNDING

  • NSERC Discovery Grant:

Towards a better understanding of SLD dynamics and its impact on in-flight icing (5-year support, 2017-2022)

The ongoing developments aim at producing “numerical experiments” of high-speed single droplet impingement, which are then used in generating a numerical database of droplet ensemble behavior. This is accomplished through two main approaches: mesh-based Level-Set Method (LSM), and mesh-less Smoothed Particle Hydrodynamics (SPH).

  • NSERC Industrial Research Chair

Multiphysics Analysis and Design of Aerospace Systems (5-year support from 2015-2021)

The research conducted under this grant is co-sponsored by:

    • Lockheed Martin Corporation to develop a unified Finite-Element based approach for flows ranging from subsonic to hypersonic speeds, including the physics associated with each regime.
    • Bell Flight for the development of numerical tools to simulate the multiphysics of rotorcraft subject to in-flight icing: ice accretion and shedding, iced rotors structural dynamics, and optimization of ice protection systems.
  • MITACS ACCELERATE GRANT

All-Mach 3D Aerodynamic Design System (HALO3D) for Next-Generation Hypersonic High-Altitude Low-Orbit Commercial Aircraft (2020-2022)

The research conducted under this grant is co-sponsored by:

    • Lockheed Martin Corporation and ANSYS, for the development of a Direct Simulation Monte Carlo solver for rarefied gases and its seamless linking to a Navier-Stokes continuum solver.
