“…Because CEDRE is also used for aeronautic combustion and solid propulsion applications for which the aforementioned simplifications are not applicable [29], the Lagrangian method uses Eq. 3, while the Eulerian method relies on the simplified formulation of Eq.…”

This study provides a comparison between an Eulerian and a Lagrangian approach for simulation of ice crystal trajectories and impact in a generic turbofan compressor. The engine-like geometry consists of a one-and-a-half stage (stator-rotor-stator) compressor in which the computed air flow is steady and inviscid. Both methods apply the same models to evaluate ice crystal dynamics, mass and heat transfer, and phase change along ice crystal trajectories. The impingement of the crystals on the blade surfaces is modeled assuming full deposition for comparison and validation purposes. Moreover, the effect of ice crystal diameter and sphericity variations on impinging mass flux and a

“…However, it is important to note that volume fraction corrections are small compared to corrections on the particle's self-induced velocity Ireland and Desjardins (2017). As most practical applications involve moderate but finite particle Reynolds numbers Hervo et al (2018); Norde et al (2019), the range of validity of eq. ??…”

“…L D,s > 6 d p , may also be necessary for stability reasons if the hydrodynamic forces acting on the particle are large. Thus, the present procedure may typically be recommended for two-phase flow simulations involving important local refinements such as reactive two-phase LES's of aeronautic combustion chambers Hervo et al (2018) and dispersed two-phase flows in resolved turbulent boundary layers.…”

This paper presents Ice Crystals particles trajectory simulations based on models representative of aircraft engines flying through realistic Ice Crystals clouds. The current study pursues of the work performed by Safran Aircraft Engines in the framework of the High Altitude Ice Crystals (HAIC) European research project. Results of the HAIC/High Ice Water Content (HIWC) projects flight campaigns are used to characterize the atmospheric environment in the Ice Crystals clouds. The present work benefits from the mixed-phased and glaciated particles trajectory modeling capabilities available in ONERA's icing numerical tools. Simulations are run on two distinct geometries: a generic engine Inlet & Fan, and a generic Fan & Low Pressure Compressor. The first configuration allows the effects of centrifugation and fragmentation on particle concentrations at the engine's primary flow inlet. The influence of particle size is also studied. The second geometry provides qualitative information on preferential accretion sites within the engine. Simulation results obtained for this configuration are consistent with experimental observations of the so-called plateau effect.
