The invention discloses a two-dimensional vortex demonstration system and method based on heat convection method, which includes a soap bubble generating device, a soap bubble receiving device, and the soap bubble receiving device includes a liquid container for carrying soap bubbles and soap liquid; heating Device, soap liquid replenishment device, soap liquid replenishment device comprises soap liquid conveying pipe, is arranged on the liquid storage part of soap liquid conveying pipe one end and is arranged on the liquid outlet head of soap liquid conveying pipe other end; Soap bubbles are generated on the liquid container, the liquid outlet head is combined with the top of the soap bubbles to replenish soap liquid for the soap bubbles, and the heating device heats the liquid container. The soap liquid replenishment device in the system continuously replenishes soap liquid for soap bubbles, so that the existence time of soap bubbles is greatly extended. By heating one side of soap bubbles, local heat convection is formed, forming Two-dimensional vortex, which can show the process of vortex formation on soap bubbles.
Description
technical field [0001] The invention relates to the technical field of simulation demonstration, in particular to a two-dimensional vortex demonstration system and method based on a thermal convection method. Background technique [0002] Vortexes are a distinctive feature of fluid flow, whether small engines, turbulence, or planetary atmospheres, and understanding the displacement of vortices, their structure, and their long-term dynamics is critical to these aspects. [0003] The vortex motion of fluids exists in a large number in nature, such as cyclones, anticyclones, tornadoes, typhoons, etc. in the atmosphere. The vortex motions in the atmosphere are closely related to the formation and development of weather systems. Tropical cyclones can be reasonably modeled by a modified version of the Rankine vortex ideal vortex. However, many problems remain when it comes to predicting their trajectories and intensity evolution, mainly because of complex environmental interactio...
