Eigenfrequency of Hydraulic Systems of Loading Device
Eigenfrequency of hydraulic systems belongs to important dynamic quantities. If the excitation frequency of a given hydraulic system is equal to the system eigenfrequency, high-amplitude pressure and flow pulsations can arise. It has a negative influence

Incorporation of Fluid Compressibility into the Calculation of the Stationary Mode of Operation of a Hydraulic Device at High Fluid Pressures [PDF]
This paper is concerned with assessing the correctness of applying various mathematical models for the calculation of the hydroshock phenomena in technical devices for modes close to critical parameters of the fluid. We study the applicability limits of the equation of state for an incompressible fluid (the assumption of constancy of the medium density)

A catalytic air recirculating medical device reduces formaldehyde levels in a simulated operating room environment [PDF]
Electrosurgery produces formaldehyde. A catalytic material was interfaced with an air recirculation device and tested for formaldehyde removal. When catalyst and activated carbon were in the device, formaldehyde levels were reduced by up to 72% after 1

Utilization of the tractor hydraulic device to operate reciprocating mowers [PDF]
Due to the ease and excellence of the hydraulic transmission, this research is concerned to transmit power from tractor to a reciprocating mower using a hydraulic cycle. The theoretical consideration and the previous results from different studies were used to determine a suitable of a hydraulic motor, which give a sufficient torque needed to cutting ...

Hydraulic and thermal characterization of a family of thermo-hydraulic separators [PDF]
Thermal-hydraulic separators (or hydraulic dispatchers) are flow collectors of relatively small size, connecting two or more hydraulic networks; they are mainly used to reduce the hydraulic interference of primary (e.g.
