Problems solved by technology

[0003] After the environmental wind tunnel snowfall experiment, a lot of snowfall will accumulate at the bottom of the experimental section. Under the existing technology, natural melting or secondary heating is generally used to melt snow. When natural melting is used, the snow melting time is longer. It will affect the next experiment arrangement; when using secondary heating, not only additional heating equipment is required, but also further energy consumption, resulting in energy waste

Description

technical field [0001] The invention relates to the technical field of experimental wind tunnels, in particular to an environmental wind tunnel and a method for melting ice and snow thereof. Background technique [0002] A wind tunnel is a wind tunnel laboratory, which is a pipe-shaped experimental device that artificially generates and controls airflow to simulate the flow of air around an aircraft or entity, and can measure the effect of airflow on entities and observe physical phenomena. , it is one of the most commonly used and effective tools for aerodynamic experiments. [0003] After the environmental wind tunnel snowfall experiment, a lot of snowfall will accumulate at the bottom of the experimental section. Under the existing technology, natural melting or secondary heating is generally used to melt snow. When natural melting is used, the snow melting time is longer. It will affect the next step of the experimental arrangement; when the secondary heating method is ...
