In this study, we numerically simulated nitrogen injection for oil reservoir development and explored the oil–gas two-phase flow model its finite difference solution method. A mathematical incorporating both gas phases was constructed, which fully considered compressibility along with Darcy's law gravitational effects in flow. The discretized using method, implicit pressure explicit saturation (IMPES) approach employed to obtain numerical solution, analyzing variation patterns of saturation,...
Mechanical properties and microstructure of friction stir-welded AZ31 based on variety post-weld heat treatment (PWHT) temperatures were evaluated, an optimal PWHT condition was identified. At rotational speed 1200 rev min −1 welding 300 mm , the average yield tensile, tensile strength elongation joints 92.5 MPa, 199.1 MPa 7.3%, respectively. It found that (300°C – 1 h) after more beneficial than other treatments in enhancing mechanical homogenising grain size. The maximum 139.9 238.4...
The Ni modified layers were prepared on the surface of Ti6Al4V substrate by plasma alloying technique. and cross-section morphology, composition distribution phase structure analysed. Nanoindentation tests performed not only but also substrates treated untreated plates. residual indentation profiles investigated. results show that uniform compact. consisted an outer deposition layer, a middle rich layer inner poor layer. concentration gradually decreased from to interior. maximum content...
The fatigue fracture behaviour and thermographic analysis of friction stir-welded (FSW) AZ31 was studied. It showed that at the advancing side (AS). Heat-affected zone (HAZ) contained a greater fraction coarse grains small amount twins. in thermo-mechanically affected were smaller, indicating may originate from incompletely dynamic recrystallisation during FSW. nugget is composed equiaxed caused by recrystallisation. During cyclic deformation, hysteresis loops AS FSW joints with stain...
Sapphire crystals are used in the manufacture of LEDs, optical window materials, etc. The presence air bubbles crystal affects properties material. If position bubble is determined, can be bypassed for subsequent slicing to obtain pure high quality sapphire crystal. At present, detection and identification still rely on human eye observation empirical judgment, which inefficient easily harmful eye. It necessary propose a highly efficient method machine vision instead detection. Based...
The fluid magnetic abrasive (FMA) is a new type of precision finishing abrasives. workpiece can be finished by because its rheological property. On base researching on the micro-structure (FMA), this paper analyzed mechanism. And experiments and results are presented as well in paper.
In order to effectively improve the accuracy of temperature measurement in low environment polar ice sheet, we designed a multi-point platinum resistance flexible chain based on Pt1000, which has advantages resistance, power consumption and high accuracy. The consists master multiple slaves. is used read entire chain's data make exchange with external equipment. slave collect upload data. RS485 bus communication between circuit directly measures ratio bridge output voltage input calculate...
