Anti-Icing System Simulation Using CANICE

Thermal Analysis and Testing of Nonrotating Cone with Hot-Air Anti-Icing System

“…Assuming the shape of the water droplet is spherical, the drag coefficient C D can be modeled by [44] C D 24 Re rel · 1 0.197 Re 0.63 rel 2.6 × 10 −4 Re 1.38 rel (4) where the relative Reynolds number is given by…”

“…Computational codes have been developed by NASA (ANTICE [19], LEWICE [20]), McGill University (FENSAP-ICE [21]), ONERA [22], Boeing [23], Ecole Polytechnique de Montreal (CANICE [24]), DAR [25], et al The icing analysis consists of four basic steps [1]: computation of aerodynamic flow, determination of supercooled water droplet trajectories and local collection efficiency, thermal balance analysis of the air-water-ice-body system, and determination of the shape of the ice accretion. The flowfield around the body can be obtained by solving Euler or Navier-Stokes (N-S) equations.…”

A Computational Modeling for Semi-Coupled Multiphase Flow in Atmospheric Icing Conditions

“…The first problem is intended to compare the exact analytical and numerical solutions as a verification study. The second problem is the air-mixed droplet flow around an airfoil taken from Morency et al (1999) as a validation study. The conditions, which represent the shadow (very low density of droplet) and high LWC (very high density of droplet) regions in Fig.…”

“…Nevertheless, the new scheme shows the robust characteristics with regard to the grid topologies. In order to validate the new scheme, experimental test cases are selected from the literature (Morency et al 1999;Silveira et al 2003;Vu et al 2002). From the literature survey, the local collection efficiency is defined as the normalized influx of droplets at a given location, (Bourgault et al 1999), where the velocity …”

“…The Eulerian approach treats the particle phase as a continuum and develops its conservation equations on a control volume basis in a similar form as that for the fluid phase. The Lagrangian approach considers particles as a discrete phase and tracks the pathway of each individual particle, such as the NASA LEWICE and ONERA codes (Hamed et al 2005;Wright et al 1997;Morency et al 1999;Silveira et al 2003;Vu et al 2002). In the Lagrangian formulation, the trajectory of each particle is computed using a force balance equation.…”
