This paper investigates the coupling characteristics of motion and heat transfer between airflow and ice crystals in a single-stage compressor. The motion and phase transition process of ice crystal particles were modeled using the Eulerian trajectory method and validated. The heat and mass transfer processes between airflows in compressor and ice crystals were simulated and analyzed. The melting ratio, catching efficiency, and sticking efficiency of ice crystals were obtained, as well as variations in temperature and humidity ratio in the airflow due to ice crystal phase change. The results show that the ice crystals sticking to blades in the single-stage compressor account for 10.35% of the impact mass flow rate. Additionally, the presence of ice crystals causes a 0.466 K decrease in the airflow temperature and a 0.114 g/kg(a) increase in the humidity ratio. The theoretical model and calculation method provide strong support for future ice crystal icing simulations and engine operation research.
