Abstract: Damage caused by displacement of a rotating shaft is prevented with an acceleration sensor. A centrifuge according to the present invention includes a rotor, a driving source that rotates the rotor, a rotating shaft that links the rotor with the driving source, an acceleration sensor, and a control unit. The acceleration sensor outputs a value indicating acceleration in at least two different directions which are orthogonal to an axial direction of the rotating shaft. The control unit obtains a displacement conversion value corresponding to a value, which is obtained by dividing a value which is proportional to acceleration based on a value indicating acceleration and outputted by the acceleration sensor, by a value which is proportional to a square of an angular velocity of the rotor, and stops rotation of the rotor when the displacement conversion value satisfies a displacement determination criterion which is predetermined and indicates that displacement is large.

Abstract: A device and a method for reducing wind resistance power of a large geotechnical centrifuge are provided. A semicircular tube cylindrical cooling device is provided between an internal side of a high-speed rotor system and a cylindrical shell. A serpentine top semicircular tube cooling plate is provided right above a hanging basket, and return helium gas inlet holes are provided at a center of the top semicircular tube cooling plate. A helium gas in a helium gas storage tank passes through helium gas outlets on the helium gas inlet pipes, and enters a centrifuge chamber from a bottom sealing plate. The helium gas is used to replace air in the centrifuge chamber to reduce the wind resistance power and corresponding energy consumption. No vacuuming is required, so sealing requirements are lower. Heat dissipation equipment is placed inside the centrifuge chamber, and a helium gas circulation wind duct is added.

Abstract: Water purification occurs under the influence of cold plasma obtained in water, which has a two-phase state, in which water and the smallest bubbles filled with gases dissolved in water are simultaneously present in the turbulence zone. The plasma is ignited inside the gas bubbles when exposed to an electric high-voltage nanosecond pulse. Since the turbulence zone located behind the flow body is saturated-saturated with fine bubbles, the plasma discharge in the bubbles becomes voluminous and diffuse in consistency. The combination of the hydrodynamic effect on water by the flow body and the generation of reactive oxygen species (ROS) in a volumetric plasma discharge in the turbulence zone causes a synergistic effect that increases the efficiency of water treatment.
