FENSAP-ICE: A Second Generation 3D CFD-based In-Flight Icing Simulation System

FENSAP-ICE is a second generation CFD-based in-flight icing simulation system, bringing to the icing field simulation advances widely used by the aircraft and turbo machinery industries. It is built in a modular and interlinked fashion to successively solve each of flow, impingement, accretion, heat loads and performance degradation via field models based on the Euler/Navier-Stokes equations for the clean and degraded flow, and new partial differential equations for the other three icing processes. This paper presents the FENSAP-ICE system and shows examples of its use to calculate impingement and ice shapes on a 3D helicopter rotor blade tip and on a nacelle inlet.
