“…Similar for in-flight icing, CFD models could provide useful information to help improve ground-deicing activities. To the best of the authors’ knowledge, the only study in the literature that aims to model aircraft ground deicing by CFD is that of Yakhya et al (2019). It presents an impinging spray model coupled to a film model using the volume of fluid (VOF) method.…”

“…In aircraft ground deicing, the liquid film formed gain mass at each time step while it is fed by the spray and also the ice melting. Similar to Yakhya et al (2019), the VOF method for the film modelling is then more interesting in the proposed case study. Given the proposed model constrains, the impinging spray model with Lagrangian particles and Eulerian film is superior to other impinging spray models.…”

Purpose The aim of this paper is to present a Eulerian–Lagrangian model of aircraft ground deicing that avoids the scale’s dispersion problem caused by the great distance between the spray nozzle and the surface to be deiced. Verification is done using the case of a hot particle liquid spray impinging on a horizontal flat plate. The impinged particles flow outwards radially from the impingement zone and form a hot film wall. The computed wall heat distribution is verified. In the end, an inclination spray’s angle study is presented. Design/methodology/approach The problem is divided into two regions. First, a 3D region is created for the evolution of the Lagrangian particles spray. A second 2D region is provided for the formation of a liquid film. The two regions exchange mass, momentum and energy through an interface. Heat losses are modelled through particles and liquid-film cooling and evaporation, particles splash and heat transfer to a fixed temperature plate. Findings For a chamber pressure of 1 bar, the predicted spray penetration is within 10 per cent of the experimental results. For this study case, the heat transfer is maximized with an inclination angle of approximately 30° of the spray. Originality/value The model presented makes it possible to simulate the impingement and heat transfer of a large-scale liquid spray with a reasonable computational cost. To the best of the authors’ knowledge, this model is a first attempt of the computational fluid dynamics simulation of ground deicing.
