The planetary gearbox, due to its unique mechanical structures, is an important rotating machine for transmission systems. Its engineering applications are often in non-stationary operational conditions, such as helicopters, wind energy systems, etc. physical structures and working conditions make the vibrations measured from gearboxes exhibit a complex time-varying modulation therefore yield complicated spectral structures. As result, traditional signal processing methods, Fourier analysis,...
In this paper, a series of fracture conductivity experiments were designed and conducted by an American Petroleum Institute (API) standard evaluation system. The mixing proportion quartz sand ceramic was optimized. By the proppant breakage rate sphericity analysis mixed with different volume proportions (PS), mixture evolution behavior analyzed. Results study showed that between pure under same conditions. For 20/40 mesh proppant, small amount (25%) in could obtain 1.27-3 times higher than...
Considering the characteristics that fracture conductivity formed by hydraulic fracturing varies across space and time, a new mathematical model was established for seepage flow in tight gas fractured vertical wells which takes into account effects of dual variable stress sensitivity. The Blasingame advanced production decline curves were obtained using finite element method with hybrid elements. On this basis, time sensitivity on curve analyzed. study shows mainly reduces value at early...
Abstract Threshold pressure gradient has great importance in efficient tight gas field development as well for research and laboratory experiments. This experimental study is carried out to investigate the threshold detail. Experiments are with without back so that effect of pore on may be observed. The trend increasing or decreasing totally opposite cases considering not pressure. results demonstrate reservoirs influence gradient. effects other parameters like permeability water saturation,...
Abstract The irreducible water saturation ( S wir ) is a significant parameter for relative permeability prediction and initial hydrocarbon reserves estimation. However, the complex pore structures of tight rocks multiple factors formation conditions make difficult to be accurately predicted by conventional methods in gas reservoirs. In this study, new model was derived calculate based on capillary fractal theory. incorporated different types immobile considered stress effect. dead or...
Cable-less micro-robots have exhibited promising potential for conducting tasks in small and constrained environments through remote controlling approaches. Soft robots formed by magnetic composites drawn rising attention, demonstrated their capability to be wirelessly controlled both dry wet working environments. This paper presents a swimmer propelled its undulatory deformation using magnetoelastic composite material. The can move freely on water surface driven field generated 3D Helmholtz...
Aiming to solve the problem of oil-air lubrication failure caused by high working temperature high-speed rolling bearings, this study proposes a method, based on theory gas-solid two-phase flow and bearing tribology, predicting dynamic rise nonlinear bearings under conditions. The accuracy fluid–structure coupling model is verified comparing test results angular contact ball at different speeds. characteristics circulation relationship between parameters heat balance have been studied. show...
