  Introduced a novel dynamically load-balanced polynomial adaptation method for Large Eddy Simulations (LES) of unsteady flows in the vicinity of complex geometries using the flux reconstruction scheme.Explored the utility of the vorticity-based adaptation indicator for moving and deforming domains.Achieved a notable speed-up of 400% to 600% in Large Eddy Simulations (LES) of unsteady flows in both fixed and moving or deforming domains.Optimized parallel computation of high-order simulations on Compute Canada HPC systems.Contributed to the development of the Computational Aerodynamics Laboratory (CAL)’s High-Order Unstructured Solver. Show less Next-generation aircraft must be cleaner, quieter, and more fuel efficient to reduce their environmental impact. At the Concordia Computational Aerodynamics Laboratory, we research, implement, and demonstrate the capabilities of novel computational tools that can be used for aerodynamic analysis and design. Our objective is to provide these cutting-edge tools to the aerospace industry, enabling them to design optimal aircraft with reduced environmental impact.[1][1] https://users.encs.concordia.ca/~bvermeir/index.html Show less

  Developed a gradient-free aerodynamic and aero-acoustic shape optimization framework for the propeller blades of electric Vertical Take-off and Landing (eVTOL) aircraft.Achieved an optimized configuration for aft propellers using the developed optimization framework, allowing the use of two-bladed aft propellers instead of four-bladed ones. Designed and optimized the winglet of the LimoConnect, a 7-seat eVTOL aircraft, resulting in a 10% reduction in drag during landing missions and performance improvements in cruising missions, validated through simulations.Participated in the conceptual and preliminary design phases of LimoConnect by conducting comprehensive analyses of flight performance by running CFD simulations and assessing aerodynamic efficiency through detailed evaluation of simulation results.Collaborated in establishing the flight envelope in accordance with the Federal Aviation Regulations (FAR) Parts 23, 25, and 27, ensuring regulatory compliance.
