Simulation Analysis and Experiment of Variable-Displacement Asymmetric Axial Piston Pump
Applied Sciences, 2017 The variable displacement pump control system has greater energy-saving advantages and application prospects than the valve control system. However, the variable displacement pump control of differential cylinder is not concurrent with the existing ...

A kinematic investigation of the influence of anvil air flow over convective nephsystems on high-level horizontal flow [PDF]
The interactions between horizontal ambient flow and divergent wind fields, such as those that obtain atop cumulonimbus complexes, were investigated (theoretically) kinematically. The following were observed from the results of the analyses. First, for a

Theoretical monochromatic-wave-induced currents in intermediate water with viscosity and nonzero mass transport [PDF]
Wave-induced mass-transport current theories with both zero and nonzero net mass (or volume) transport of the water column are reviewed. A relationship based on the Longuet-Higgens theory is derived for wave-induced, nonzero mass-transport currents in ...

Efficient placement technology of proppants based on structural stabilizers
Petroleum Exploration and DevelopmentFiber is highly escapable in conventional slickwater, making it difficult to form fiber-proppant agglomerate with proppant and exhibit limited effectiveness. To solve these problems, a novel structure stabilizer (SS) is developed.
