The invention belongs to the technical field of observation equipment, and particularly relates to a frosting experiment device and application. An existing measuring device cannot directly observe the surface flow field characteristics of a frost layer under supersonic speed and the influence of shock waves on the frost layer, and there is no appropriate model for predicting the frosting amount. The invention provides a frosting experiment device which comprises a schlieren generation mechanism, a high-speed air duct and a temperature control mechanism, the schlieren generation mechanism comprises a light source assembly and a schlieren observation assembly, the light source assembly is arranged on one side of the high-speed air duct, and the schlieren observation assembly is arranged on the other side of the high-speed air duct. The temperature control mechanism is arranged in the high-speed air duct, and when high-speed airflow in the high-speed air duct passes through the temperature control mechanism, th
