The invention relates to an airflow device in which there are adjusters in the flow path to alter the flow geometry of the air.
Noticeably more quiet due to Whispering nozzle which has optimized air flow geometry.
Shearing is achieved using a mobile surface and immobile surface, or other flow geometry, under conditions providing for a transient phase separation.
The minimal fluid interconnects and simple flow geometry makes the device easy to use and implement, economical to fabricate and operate, and robust in its operations.
Changing the nozzle flow geometry results in changing the nozzle HSI, which is beneficial to optimize drilling different rock formations in different drilling environment.
The invention relates to an air filter comprising a prefractionator having an optimised inflow form, the outflow form of the prefractionator corresponding to the inflow form of a filter element.
