Sulfate-reducing bacteria (SRB) corrosion is one of the main reasons leading to service failure engineering materials in marine environment. An understanding SRB especially under continuous organic carbon starvation required. In this work, X80 pipeline steel was studied using mass loss, electrochemical measurements, and surface analysis. The effects initial concentrations on were also discussed. results indicated that more than 99% population die after 21 d testing various conditions, but...
Fluidic oscillators have emerged as a prominent topic of research in the field flow control, owing to their broad sweep range and enhanced control efficiency. However, underlying mechanisms governing operation fluidic remain poorly understood, effect oscillation frequency on performance has yet be conclusively determined. In this study, novel oscillator is proposed that achieves decoupling by replacing conventional feedback channel with synthetic jets, thereby enabling modulation at constant...
Flow control can effectively improve lift and delay flow separation. Sweeping jet (SWJ) actuators have attracted increasing interest for as active actuators. In this paper, the characteristics of SWJ actuator were studied through large-eddy simulation experiments. It was discovered that oscillation frequency is directly proportional to mass rate, its working principle determined. Subsequently, with [Formula: see text], 1.9%, 6.6% applied on hump airfoil. observed an increase in momentum...
A fast solution of supersonic flow is one the crucial challenges in engineering applications flight. This article introduces a deep learning framework, physics-constrained network (SPC), for rapid unsteady problems. SPC integrates convolutional neural networks with methods based on Euler equation to derive new loss function that can accurately calculate fields by considering spatial and temporal characteristics at previous moment. Compared purely data-driven methods, significantly reduces...
In this work, a novel graphene oxide (GO)/SiO2-based nanocontainer loaded benzotriazole (BTA) was synthesized by one-step method. The self-healing epoxy resin coating with high corrosion resistance based on GO-SiO2-benzotriazole (GS-BTA) nanocontainers prepared. Electrochemical impedance spectroscopy (EIS) and wire beam electrode scanning (WBE-EIS) measurements were used to evaluate the long-term anticorrosion properties of coatings, respectively. Results indicate that GS-BTA is largely...
Sweeping jet (SWJ) actuators have become a hot research topic in flow control due to their larger sweep range and higher efficiency. However, the linear relationship between frequency velocity ratio (VR = Ujet/U∞) SWJ actuator makes it challenging determine dominant factor affecting effect. Decoupling VR determining mechanism of is, therefore, difficult task. In this study, novel type was designed using periodic synthetic jets instead feedback channels. This achieved implementation different...
In this paper, quasi-static and dynamic compression experiments were carried out on polyethylene foam by a universal material testing machine drop tower impact device. The mechanical response characteristics energy absorption capacity of under moderate strain rate (4 × 10 −3 –10 2 s −1 ) loading conditions obtained. An improved constitutive model strain-rate term coupling was established based the Sherwood–Frost phenomenological Johnson–Cook model. Low Density Foam combined in finite element...
Deepwater subsea wellheads may be significantly threatened under extreme sea conditions and operations, especially when the seabed is composed of very soft clay properties. A numerical model a deepwater wellhead system established using classic ocean pipe element nonlinear spring ANSYS to examine behaviors in diverse soil. Nonlinear elements coded APDL language are used three types soils: soil, firm The dynamic quasi-static typical coupled decoupled models drilling riser particularly...
As an active flow control technology and with the advantages of no moving components, Sweeping jet actuator has become a hotspot in field control. However, linear relationship between oscillation frequency momentum coefficient sweeping makes it difficult to determine dominant factors that affect effectiveness. Decoupling coefficient, as well determining mechanism, is focus studying actuator. In this study, novel designed using synthetic jets instead feedback channels applied separation...
Power QFN use solder paste attach power die to achieve high electrical conductivity and thermal conductivity, but the flux which come from can contaminate lead frame surface during reflow process. We also have clean process remove residue by organic solvent. However, can't be removed completely solvent it down bond non-stick low wire peel strength issue etc. In this paper, we introduce a new method is more convenient less environment pollution. Firstly, covers whole L/F surfactant shaped...
