1. What is the Karman vortex street phenomenon? Karman vortex street phenomenon is an important phenomenon in fluid mechanics. When a steady incoming flow under certain conditions bypasses certain objects, double row vortices with opposite rotation directions and regular arrangement will periodically detach on both sides of the object. These vortices, after undergoing nonlinear effects, will form Karman vortex streets. The formation conditions of Karman vortex street: Fluid conditions: require a certain flow velocity and seepage flow state, usually in laminar or turbulent flow. The shape of objects, such as bridge piers, towers, chimneys, and electrical wires, has a significant impact on the formation of Karman vortex streets. The vortices generated by these objects in the fluid can easily form Karman vortex streets. The natural phenomenon of Karman vortex street: In nature, Karman vortex street phenomenon is very common. For example, when water flows over a bridge pier, alternating shedding vortices will form on both sides of the pier; When the wind blows over buildings such as towers and chimneys, it also forms Karman vortex streets around the buildings. Application of Karman vortex street: Engineering field: The Karman vortex street phenomenon has a significant impact on the wind-induced vibration and stability of many engineering structures, such as bridges, high-rise buildings, transmission lines, etc. Therefore, in engineering design, it is necessary to consider the influence of Karman vortex street and take corresponding vibration reduction measures. Fluid measurement: The Karman vortex flowmeter is a flow measurement instrument made using the Karman vortex principle. When a fluid flows through a vortex generator, vortices alternate on both sides of the generator. By measuring the shedding frequency of the vortices, the fluid velocity and flow rate can be calculated. In summary, the Karman vortex street phenomenon is an important phenomenon in fluid mechanics, with broad application value and significant research significance.

2. What is the difference between vortex flowmeter and balance flowmeter?

Vortex flowmeter and balance flowmeter are two mainstream instruments in industrial flow measurement, and their core differences are reflected in the following aspects:

1. Differences in measurement principles Vortex flowmeter: Based on the Karman vortex phenomenon, the flow rate is calculated by detecting the alternating vortex frequency generated when the fluid flows through the vortex generator, and the frequency is linearly related to the flow rate.

II. Comparison of Nuclear Structure and Performance

III. Preferred Application Scenarios: Vortex flowmeters are preferred for clean gas/steam volume flow measurement, medium and low temperature environments (such as conventional steam pipelines), and scenarios with limited budgets and low maintenance requirements.
