Multiparameter coupling droplet evaporation experiment channel

Abstract

The invention discloses a multiparameter coupling droplet evaporation experiment channel. The channel is circular and comprises a fan section, a temperature adjustment section, a pressurization section, a flow adjusting section, a flow stabilizing section and an experimental section which are sequentially connected end to end, and an operation console, a heater and a radiation determinator are arranged in a test section. Compared with the prior art, the channel disclosed by the invention has the advantages that a fan, a heating wire and a booster pump are respectively connected with a controlsystem, power of the fan, the heating wire and the fan is controlled by virtue of a signal of an acquirer, and realization of stable states of wind speed, temperature and pressure in an evaporation chamber can be facilitated; the radiation determinator is mounted on a lifting operation console and at the same height with the lifting operation console, and radiation degree change in an evaporationprocess can be determined; a flow adjusting grating is arranged at a bend, so that airflow disturbance in the channel is smaller; a flow adjusting layer is arranged in the flow adjusting section, so that inlet air of the experimental section is more uniform; and a glass window is arranged in the outer wall of the evaporation chamber, and droplet form change in the evaporation process can be monitored in real time.

Description

technical field [0001] The invention relates to the technical field of evaporation, in particular to a droplet evaporation experiment platform with variable wind speed, temperature and pressure. Background technique [0002] With the in-depth study of the droplet evaporation process, the precise control of process parameters is more and more important for the correct analysis of the droplet evaporation process mechanism. The droplet shape, temperature and radiation that change in real time during the evaporation process are very important process parameters. However, judging from the domestic and foreign research on evaporation technology and the development of evaporation equipment, there is currently no evaporation experiment platform that can simultaneously accurately record and measure the real-time changes in droplet shape under different ambient airflow velocities, temperatures and radiation intensities. , Most of the existing evaporation experiment platforms can only...

However, judging from the domestic and foreign research on evaporation technology and the development of evaporation equipment, there is currently no evaporation experiment platform that can simultaneously accurately record and measure the real-time changes of droplet shapes under different ambient airflow velocities, temperatures and radiation intensities. , most of the existing evaporation experiment platforms can only conduct droplet evaporation experiments under the condition of changing a single variable, and cannot study the influence of multi-parameter coupling at the same time. The experimental operation is complicated, which is not conducive to the in-depth study of the evaporation mechanism.
