Icing and Anti-Icing Systems
|(Full screen view)|
Flight safety of aircraft operating under natural icing conditions is one of certification authorities major concern, as well as that of aircraft manufacturers.
Under the direction of Professor Ion Paraschivoiu, the objectives of the icing projects within the J.-A. Bombardier Aeronautical Chair (now known as the Aerodynamics Laboratory) of École Polytechnique de Montréal (Canada) are geared toward the development of reliable numerical tools for the simulation of ice accretion and anti-icing systems (the CANICE computer code).
CANICE can predict the ice accretion on single and multi-element airfoil/wing and evaluate the performance degradation due to the presence of ice. Recently, the J.-A. Bombardier Aeronautical Chair developed the innovating CANICE-3D code to simulate 3-D ice accretion and optimize the anti-icing flow and heat requirements for aircraft anti-icing system.
Currently, the main focus of the icing projects at the Aerodynamic Laboratory is related to the development of CANICE3D-NS, a CFD based 3-D ice accretion and anti-icing simulation code. CANICE3D-NS is configured to work with a parallel multi-block CFD code, which is an Euler/Navier-Stokes (RANS) 3-D compressible flow solver that uses a cell-centered, finite volume discretization method applied on curvilinear block structured (multi-block) grid.
