To study the erosion–corrosion characteristics of TP140 casing steel and 13Cr tubing in oil fields, we performed gas–solid liquid–solid jet flow experiments to control particle addition, angle, velocity measure erosion corrosion components. Meanwhile, used a standard three-electrode system changes electrochemical parameters on metal surface two-phase containing 2 wt % NaCl. Results showed that is mainly dominated by velocities impact angles particles, rate affected liquid rate. The rates two...
Based on a novel triazine compound, the properties of tanned leather and commercial feasibility in pilot scale have been investigated. Then this approach tanning was compared with conventional chrome tanning: condition less-salt pickling free, physicochemical including thermal stability mechanical strength were analyzed. Meanwhile, surface roughness fiber dispersion evaluated as well. The results show that compound are similar to leather, bundle is well-dispersed much evener than treating....
Wettability is important for photodynamic film sterilization since higher wettability enhances the capture of bacteria in contact with photosensitizers. Herein, a small number violet phosphorus quantum dots (VPQDs) are anchored into hypericin bacterial cellulose films (VP/Hy-BC films) to improve wettability, reducing water angle from 56.8° 33.0°. This modification facilitated more effective interactions between and photosensitizers, rapidly inactivating 7 log
Abstract The improvement of anti‐corrosion performance and enhancement functionality in coatings are essential. Boron nitride (BN), as a two‐dimensional thermal conductive filler, is incorporated into composite to provide corrosion resistance conductivity. combination BN with zero‐dimensional filler alumina (Al 2 O 3 ) proves be an effective method for enhancing the conductivity coatings. In this study, micro (Micro‐Al and/or nano (Nano‐Al were combined integrated waterborne epoxy resin...
The present work investigates diffusivity of hydrogen (H) in palladium-silver (Pd/Ag) over 300～1100K temperature range for Pd 100-x Ag x , X=0%～40% by using the Sievert Law. silver Pd/Ag alloy has significantly higher diffusion as compared to pure sensor, addition reduces critical α→Β phase transformations and also increases solubility H, provides longer operational lifetime sensor. It was found that coefficient H decreases with increasing temperature, calculated alloys were have a maximum...
The processes of HTHP well fracturing, oil drive, and gas recovery are accompanied by the non-stationary flow medium in tubing, which may lead to periodic vibration cause failure fatigue thread leakage, bending deformation. In this paper, a fluid–structure interaction model with 4-equation was established, considered unsteady fluid motion state tubing during injection, pump start, shutdown tubing. Further, discrete solution MOC used obtain variation rate pressure, rate, frequency, additional...
In order to solve the problems of poor tolerance traditional algal-bacterial symbiosis system high ammonia wastewater and biomass recovery, a new combining biological agents nitrifying bacteria ordinary Chlorella vulgaris was proposed. The results showed that adjusting volume ratio algae had an effect on treatment performance, microalgae growth flocculation effect. At optimal 1:3, TN, NH+4-N COD removal rates were 50%, 70%and 83%, respectively. concentration nitrogen would have some...
Abstract With the increasing requirements of aeroengine performance and working stability, primary research task rotor system dynamics is to build a model that can reflect actual situation obtain calculation results which real dynamic characteristics system. In this paper, finite element analysis power turbine was established, complex were studied. The indicated could rotor. For given design rotational speed, critical speed had enough margin worked safely smoothly. This provided reference...
Hydraulic fracturing is a new technique which used in oil yield to maximize its own production. The pumping of slurry flow through tubing collar can cause considerable mass loss inner surface materials. This may pose significantly potential risk even well loss. Especially, the erosion phenomenon particularly serious structure variable diameter. Numerical simulation this paper was get particle impact parameters, and it combined with jet experiments find out main factors BG-13Cr Finally,...
