Gas self-suction is discussed with different nozzle diameter by detecting the pressure at gas inlet.
The increase in the geometric criterion K from 3.2 to 4.8 leads to an amazing transformation from non-self-suction to the maximum vacuum degree.
The proposed foam generator has a self-suction unit that uses a turbulent-flow water jet to automatically draw in ambient air and foaming agent, thereby eliminating the need for compressed-air hoses and pipes.
The hydraulic-mechanical properties of the deposited tailings are closely coupled due to several mechanisms, such as evaporation, drainage, self-consolidation, suction and crack development.
Moreover, the obtained results support that the THMC properties of CPB are strongly coupled due to several internal mechanisms, such as heat of hydration, self-desiccation, suction development and cement hydration.
Patients were pre-oxygenated before suctioning and manually ventilated with a self-inflating bag in between suction catheter passes.
Also, suction development due to self-desiccation can significantly increase the uniaxial compressive strength values with time.
A variety of geometric sizes of a self-excited pulsed jet such as the diameter of the suction and discharge nozzle, jet chamber length and diameter, and the collision angle are the main structural parameters.
