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, the airflow can reach a supersonic speed state at the temperature control mechanism due to the fact that the flowing sectional area changes. 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.

    本申请属于观测设备技术领域,特别是涉及一种结霜实验装置及应用。现有测量装置不能直接观测超音速下霜层表面流场特性及激波对霜层的影响,没有合适的模型来预测结霜量。本申请提供了一种结霜实验装置,包括纹影产生机构、高速风道和控温机构,所述纹影产生机构包括光源组件和纹影观测组件,所述光源组件设置于所述高速风道一侧,所述纹影观测组件设置于所述高速风道另一侧,所述控温机构设置于所述高速风道内,所述高速风道中的高速气流经过所述控温机构时,由于流通截面面积发生变化,使得气流在所述控温机构处能够达到超音速状态。可以直观有效地观测超音速下霜层表面流场特性及激波对霜层的影响。
