Icing on airplanes occurs when supercooled water particles exist in the air, so studying the water-air two-phase flow field plays a vital role in providing a preliminary insight into the freezing potential of aircraft-mounted devices, thereby determining the location of sensors in the aircraft design. Geometric factors of supercooled water particles play an important role. They determine the formation of the structure of the water particle flow field, the area of water particles falling on the aircraft’s surface, and the particles’ energy. This paper introduces the solution for the water particle flow field using the finite volume Euler approach. The described algorithm makes it possible to calculate the distribution of the water content field around bodies flown around by a water suspension. The flow through NACA 0012 profile, with varying water droplet geometry parameters, is considered, thereby evaluating the influence of water particle size on the flow field. The results obtained are compared with experimental data.
