The invention discloses a spraying
nozzle cavitation flow
nanosecond flash imaging test device and method. The spraying
nozzle cavitation flow
nanosecond flash imaging test device comprises a test
system and a pipeline
system. The test
system comprises a common-rail
control system, a computer, a first
CCD camera, a second
CCD camera, a
synchronizer and a
nanosecond white illuminant flashing system. The pipeline system comprises a
liquid storage tank, a filter, a high-pressure pump, a common-rail
pipe, a pressure meter and a transparent spraying
nozzle which are sequentially connected through pipelines, wherein a
heating element and a cooling fan are arranged on the
liquid storage tank, the high-pressure pump is connected with a motor, a flow outlet pipeline of the common-rail
pipe is respectively connected to the common-rail
control system and the transparent spraying nozzle, and the pressure meter is arranged on the connecting pipeline of the common-rail
pipe and the transparent spraying nozzle. The spraying nozzle
cavitation flow nanosecond flash imaging test device and method can effectively obtain the process of generation, development and death of nanosecond vacuoles, the
heating element, the cooling fan and a temperature sensor are installed in an
oil tank, the temperature of fluid can be controlled in real time through a control panel, and conditions are provided for research of
cavitation flow of fluid in the spraying nozzle at different temperatures.
