Description

Technical Field

[0001] The invention relates to the technical field of solution drop impact force detection, in particular to a solution drop impact force real-time detection device. Background Art

[0002] The phenomenon of droplets impacting walls is widely present in daily life and industrial production, and has relevant applications in fields such as spray cooling, trace oil and gas lubrication, inkjet printing, and internal combustion engine cylinder combustion.

[0003] In specific industrial applications, such as spray cooling, the coolant is atomized into micro-droplets and then hits the workpiece surface at an angle. After continuous impact, the droplets will form a flowing film on the surface. The flow shape at the gas-liquid interface evolves in a complex manner during the entire droplet impact process. Therefore, it is necessary to use experimental equipment to study the entire process of droplet generation, droplet impact, and film formation in the droplet impact process, which provides reliable experimental data for subsequent jet breakup to form droplets and droplet impact mechanism research.

[0004] The solution drop impact force in the prior art is not convenient for accurate detection operation and is greatly affected by external factors, such as liquid remaining on the detection panel or being unable to be discharged in the form of drops, as well as dust or shaking, which can affect the detection results.

[0005] When applying for the present invention, the applicant found through search that a Chinese patent discloses a "rotating jet droplet generation and collision experimental device" with application number "202310262651.7". This patent mainly generates a large number of droplets in a short time by causing the jet to break in a rotating mode. The droplets cover a wide area, the film forming process is rapid, and the liquid film thickness is easy to measure, thereby improving the experimental efficiency and experimental accuracy.

Therefore, according to the applicant's invention, a device capable of real-time detection of the impact force of solution drops was invented, which solves the problem that the liquid remains on the detection panel or cannot be discharged in the form of drops.
