A multi-parameter coupled droplet evaporation experimental channel

Abstract

The invention discloses a multi-parameter coupling droplet evaporation experiment channel, which is in the form of a ring, and includes a fan section, a temperature regulation section, a booster section, a rectification section, a steady flow section and an experiment section connected end to end in sequence, and the test section is provided with Operating table, heater, radiometer. Compared with the prior art, the present invention has the following advantages: the fan, heating wire and booster pump are all connected to the control system, and the power of the fan, heating wire and fan is controlled through the signal of the collector, which helps to realize the wind speed and temperature in the evaporation chamber and the pressure are in a stable state; the radiometer is installed on the lifting operation platform at the same height as it, and can measure the radiation change during the evaporation process; the rectification grille is set at the bend to make the air flow disturbance in the channel smaller; the rectification section is arranged There is a rectifying layer to make the air intake in the experimental section more uniform; glass windows are installed on the outer wall of the evaporation chamber to monitor the droplet shape changes during the evaporation process 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.
