The dynamics of solid particles of complex shapes such as airborne snowflakes are governed by aerodynamic drag forces that are a function of the relative velocity of the particle in the flow and the particle drag coefficient, which depends on the par

International audience; The melting process is studied for the case of snowflakes of aggregate type. Snowflakes are placed in the center of an acoustic levitator with a warm air flow. The evolution of the shape of the snowflake is recorded over time
