Abstract: The difference between the icing problem of mixed phase/ice crystals and the supercooled water icing is presented, and the harm of the former pointed out. The research progress of mixed phase/ice crystal icing is discussed from three aspects:ice crystal icing ground simulation test equipment, experimental phenomena, and numerical simulation. The ice crystal generation methods and test capabilities of ground simulation test equipment, with the Cox ice wind tunnel, NRC high altitude test equipment, NASA's propulsion system laboratory, and Germany's Braunschweig icing wind tunnel as examples, are summarized, the mixed phase or glaciated icing experiments conducted in the above four ground simulation equipment are introduced, and the similarities and differences of the experimental phenomena and their causes are analyzed. Four key problems including the ice crystal melting phase transition during movement, the ice crystal adhesion, erosion, and the icing process simulation are then discussed in the numerical simulation of mixed phase and glaciated icing. Furthermore, the existing models and simulation methods are summarized, and the shortcomings proposed. Finally, the research directions of mixed phase/glaciated icing requiring further attention are prospected.
