Efficient development of unconventional natural gas using self-rotating cascade-nozzle bits will help accelerate the construction a sustainable energy system. However, reasons for differences in rock-failure characteristics cascade nozzles are still unclear. Experiments were conducted on sandstone and coal developed bit under different pressures. The rock-breaking influenced by nozzle arrangement parameters, jet pressure, rock lithology. pressure affect force exerted performance. central...
The aluminum alloy components on automobile often experience high strain rate deformation during accidents. dynamic behavior and constitutive model are crucial for analysis of vehicle body collisions failures. In this work, the 7A75 plate was heat treated according to standard manufacturing procedures. Quasi-static tensile experiments were conducted aged in a wide range from 0.001 s-1 500 s-1. revealed, models established. It found that has strong sensitivity, its mechanical properties can...
As an important overcurrent component in a waterjet propulsion system, the inlet passage is used to connect pump and bottom of ship. The anticavitation, vibration, noise performance are significantly affected by hydraulic passage. directly affects overall thus design optimization method part system. In this study, characteristics system with different flow parameters geometric were studied combination numerical simulation experimental verification. model test was verify results show that...
Shale gas has become one of the important contributors to global energy supply. The declining pattern production rate with time from an unconventional reservoir is due depletion shale stored in nanovoids formation. However, there are only limited ways predict variation reservoir. This multiple transport mechanisms nano-scale pores and changes permeability pressures pores, which impacted by pore structure shale. In this study, permeability-pressure (K-p) relationship for different shales...
The difficulty in understanding the flow characteristics of water jets impacting on solid surfaces made jet technology requiring further investigations. Arbitrary Lagrange-Euler (ALE) method is used to develop a numerical model surface. It also utilized describing and pressure evolution during impact process, formation mechanism zone, clarifying influence factors stagnation zone. results showed that zone was characterized by shock wave produced When contained water, it hammer stage. However,...
In this work, we explore the combustion mechanism of single micron-sized aluminum particles using a numerical model. The Burcat database and Catoire is considered as thermodynamic data kinetic for our model combustion. Two independent experiments, including particle temperature profiles, ignition delay burning time, are selected to evaluate performance shows great agreement all properties. A parametric study further conducted identify effect involved physical parameters on process. diffusion...
The competition between buoyancy and viscous force its effects on oil secondary migration patterns is investigated in our physical experiments. Considering the variation of geology fluid properties during subsurface, three series experiments were carried out by adjusting density difference water, injection flux, particle size glass beads, respectively. path structure model was observed three-dimensional reconstruction magnetic resonance image (MRI), front velocity measured. Three types...
Abstract In order to study the effect of conventional drilling gas extraction technology, combined with observation results upward and downlink field test in 81309 working face Baode Mine. The analysis data shows that under same control effect, average concentration purity uplink are higher than boreholes. range, pumping boreholes is 1.134 times boreholes, while pure flow rate 1.296 show drill Hole has better stability drilling.
The pumping station along the Yangtze River runs around zero head all year round, and work flow rate deviates from design condition, which is easy to cause hydraulic vibration, seriously affects safety of unit. By using CFD software, numeric simulation typical low Two-way system was made. characteristics pressure fluctuation two-way channel with large are calculated analysed. results verified by model tests. show: Under super pattern main area inlet outlet better, but blind end has larger...
Soil erosion always leads to decreasing of land productivity, deposition channels, lakes and reservoirs, pollution water quality so on. In the small watershed management, soil amount should be definite. The modulus is able quantitatively characterize average extent erosion. practice, it difficult ascertain modulus. Several methods are introduced in this article. Taken some Yellow River West Henan region as an example, these testified feasible ascertaining construction dam system projects...
A twisted submarine rudder was designed to reduce the unsteady force on and improve propulsion efficiency of propeller. The not only switches wake in pre-rotation state direction opposite propeller rotation but also increases mismatch between circumferential phase-angle distribution characteristics peak profile at each radius. To investigate influence this submarine’s flow field propeller’s hydrodynamic performance, shear stress transport (SST) turbulence model used calculate compare...
