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 no appropriate experience correlation formula is used for calculating 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 can move in the high-speed air channel, and the flow speed in the high-speed air channel can reach the supersonic speed. And the influence of the frost layer surface flow field characteristics and shock waves on the frost layer under supersonic speed can be visually and effectively observed.
