AI Technical Summary
Existing ice crystal simulation devices suffer from excessively high local concentrations at the center of ice crystals, small diffusion and coverage areas, and the inability to measure ice crystal concentration across flow velocity ranges, which affects the fundamental theory and engineering applications of ice crystal icing research.
An ice crystal testing device based on a negative pressure suction and recirculation wind tunnel for aircraft is adopted. By combining an ice crystal generator, a vacuum device and a recirculation wind tunnel, a stable supply and diffusion of ice crystals are achieved, and a uniform ice crystal field is formed by airflow regulation.
It broadened the applicable range of test conditions, improved the overall concentration level and flow field distribution uniformity of the ice crystal field, and realized the quantitative control of ice crystal concentration and the reliability of test data.
