Problems solved by technology
However, the atomizing nozzles currently used in medium atomization are difficult to meet the requirements of the wind tunnel test. They cannot ensure good cloud uniformity and achieve a stable and controllable average spray droplet diameter and water flow rate. Both droplet diameter and water flow are well above ideal

The invention discloses an atomization control method for an atomization nozzle, comprising: liquid flows into the atomization nozzle from a liquid inlet, enters a liquid buffer chamber through a pressure valve, and then enters a lower liquid chamber; gas enters the atomization nozzle from a gas inlet , injected into the gas buffer chamber through the gas channel; after the gas is buffered and adjusted by the gas buffer chamber, part of the backflow enters the liquid buffer chamber through the lower liquid channel, and the other part is ejected from the end of the gas buffer chamber; the backflow enters The gas in the liquid buffer chamber completes the gas-liquid premixing with the liquid in the liquid buffer chamber, and the gas-liquid mixture collides with the jet gas from the end of the gas buffer chamber at the end of the lower liquid chamber to form a violent turbulent flow state, which is then sprayed by the atomizing nozzle The spray hole is sprayed out to complete the flow fuzzy atomization process. The pressure valve automatically adjusts the flow and pressure of the liquid flowing into the liquid buffer chamber, so that the atomizing nozzle can switch between different atomizing modes.
Description
technical field [0001] The invention belongs to the technical field of atomization, and in particular relates to an atomization control method of an atomization nozzle. Background technique [0002] Atomization technology is widely used in aviation, aerospace, metallurgy, environmental protection, chemical industry, electronics, agriculture and animal husbandry and other industries. Atomization technology mainly includes two atomization methods: mechanical atomization and medium atomization. Medium atomization realizes atomization through the interaction of various working media. Achieve better atomization effect in a wide range of liquid flow. [0003] In the wind tunnel test, the important control parameters for simulating the real flight cloud environment include liquid water content, average water droplet diameter, etc. It is necessary to control the space water content under extremely low liquid flow conditions and obtain a wide particle size distribution of atomized d...
