AI Technical Summary

Technical Problem

The existing droplet suspension device can easily interfere with the propagation of the flame when observing the flame, and it is difficult to effectively observe the flame under the droplet.

Method used

A droplet evaporation and combustion experimental device including a support frame, a droplet generation and delivery system, a heating system, and a shooting and data acquisition system is designed. The device adopts a "sling" shaped structure of suspended bracket and V-shaped suspended wire hanging droplets to avoid interference from the bracket to flame, and ensures a stable high-temperature environment in the heating furnace through temperature control systems and heat insulation treatment.

Benefits of technology

Effective observation and shooting of the evaporation and combustion process of the liquid droplets is achieved, avoiding the interference of flame propagation, and providing a deeper understanding and theoretical support for atomized combustion.
