Résumé
Snow accumulation on surfaces is a significant cause of contamination and can obstruct visibility on vehicles; this can pose a significant safety hazard. To investigate snow adhesion, experiments were conducted in a controlled environment with no wind using artificial snow from a snow gun at sub-zero temperatures. Surfaces at different angles of incline were tested across a range of temperatures to observe snow accumulation. Particle data, including particle size and fall velocity, was captured using a laser precipitation monitor. Adhesion criteria defined in terms of critical velocity and critical particle radius for rolling and sliding were imposed on the collected data. Further numerical analysis of the results revealed that the tendency of snow to adhere to surfaces rises with an increase in temperature values. Non-dimensional numbers that quantify the observed phenomena were compared with experimental results from the climatic chamber. Additionally, the numerical model revealed an inverse relationship between the surface incline angle and the predicted number of particles adhering upon impact.
