A state of the art CFD analysis (OVERFLOW 2.1y) has been coupled to an industry standard ice accretion analysis (LEWICE3D) and grid generator (Chimera Grid Tools) so that temporal growth of ice over 2D airfoils may be computed in a robust automated fashion. Results are presented for a SC1095 airfoil for two conditions. The coupled methodology was used to systematically study the effects of grid density and establish grid convergence. The effects on the icing phenomena attributable to turbulence modeling and the frequency of update of the flow field were investigated. Grid convergence was established at low Mach numbers, and it was concluded that approximately 300 points in the wrap around direction, and a normal y |
