“…For We n > 5000 the ejected drop size becomes constant. As a matter of fact, the value of D 32 /D 0 tends asymptotically to 0.1, which is identical to the value incorporated into the CANICE code (Sabri et al 2007), or to the results obtained with DNS calculations by Campeanu and Papageorgiou (2018).…”

“…Ice accretion mainly results from water drops with a diameter smaller than 50 microns that freeze upon impact with aircraft surfaces (Bodoc and Berthoumieu 2019). The resulting ice shapes can be estimated by ice accretion codes that are based on drop tracking calculation, like LEWICE (Wright 2005), TRAJ2D/IGLOO (Trontin and Villedieu 2016), and CANICE (Sabri et al 2007).…”

“…The experimental investigation mainly focused on water mass retention (Papadakis et al 2002(Papadakis et al , 2003, with few insights into the drop behavior before, during and after impact. Some of the models used in the development of simulation tools for SLD icing applications (Tan 2004;Wright 2005;Sabri 2007;Trontin and Villedieu 2016) were calibrated and validated using these experimental datasets.…”

SLD icing requires the understanding of micrometer-sized droplets impacting at velocities beyond 50 m/s. This paper proposes an experimental investigation of fast impinging large droplets under non-icing conditions. Three aspects of the impact are analyzed: the splash dynamics as a function of the surface nature, the deposition rate, and the secondary drop characteristics for various primary drop characteristics. Examination of images obtained for a clean surface and for a blotter paper surface shows significant differences in terms of the amount of water reemitted. The measurement of the deposition rate confirmed that the dynamics of drop impingement on blotter paper is not the same as impingement on a clean surface. The characterization of the secondary ejected drops shows significant discrepancies with respect to the literature.

“…Usually, ice accretions result from small water drops (less than 50 microns in diameter) that freeze upon impact with aircraft surfaces. The resulting ice shapes can be estimated by ice accretion codes as LEWICE [1], TRAJ2D/IGLOO [2], CANICE [3] that are based on the droplet tracking calculation.…”

“…In developing simulation tools for icing applications, it is important to capture the effect of large drop impingement dynamics on the ice accretion process. Some of the models developed for SLD impact ( [1], [2] [3], [7]) were calibrated and validated using the experimental data of Papadakis et al [6]. The experimental data (impingement efficiency) was obtained using a dye-tracer technique, which involved spraying a known concentration of dye-drops towards the target airfoil, which was covered with blotter paper.…”

This paper proposes an experimental investigation of fast impinging large droplets in non-icing conditions. Two main aspects of the impact event are analyzed and discussed: the impact dynamics as a function of the surface nature and the deposition rate of the liquid on the impingement surface for various conditions. The data has been recorded and characterized at ambient pressure and a temperature of the air between 5 and 10°C using a vertical wind/droplet tunnel. To avoid the droplets evaporation the relative humidity was controlled. The morphology of impact was studied by backlighted imagery and quantitative results were obtained by image analysis. The deposition rate was obtained weighting the water accumulated on the impingement plate. Examination of splashing events images obtained on a clean surface and on blotter paper shows important differences in terms of secondary drop generation. The measurement of the deposition rate confirmed that the dynamics of drop impingement on blotter paper is not the same as impingement on a clean surface. These differences may significantly impact the development of models for icing applications.
