Abstract The corrosion potential of AISI 316 stainless steel (SS) and the oxygen reduction rate, as measured by cathodic polarization curve, have been determined with without formation ...
The renewable energy route map for Wales outlines ambitious targets 50% renewables by 2025. Welsh coast, subject to tidal ranges of the order 13 m and flows in excess 3 m/s, is thus an ideal position significantly contribute these targets. Tidal stream emerging sector a relatively small number devices are at various stages development Wales. However, before such demonstration or arrays can be applied larger scale, consents permissions must obtained ensure safe environmentally responsible...
As the electronics industry moves towards 21st century, environmentally conscious manufacturing is becoming a very important issue for industry. In recent years, advanced technologies have been developed automotive packing that not only are friendly, but also reduce complexity and cost, improve product quality, meet stringent reliability requirements environment. this paper, aspects of no‐clean soldering lead‐free solderr development reviewed, some most critical factors implementing...
In order to more accurately predict the coupled in-line and cross-flow vortex-induced vibration (VIV) response of deep-water marine drilling risers in linearly sheared flows, an improved three-dimensional time-domain model based on van der Pol wake oscillator models was established this paper. The impact changing added mass coefficients taken into account model. finite element, Newmark- β , Newton–Raphson methods were adopted solve nonlinear partial differential equations. entire numerical...
Abstract It is widely accepted that vortex-induced vibration (VIV) a major concern in the design of deep sea top-tensioned risers, especially when riser subjected to axial parametric excitations. An improved time domain prediction model was proposed this paper. The based on classical van der Pol wake oscillator models, and impacts in-line vessel heave motion were considered. finite element, Newmark-β Newton‒Raphson methods adopted solve coupled nonlinear partial differential equations....
In order to analyse the ultra-deep-water top-tension riser deformation in drilling conditions, a nonlinear quasi-static analysis model and equation are established. The this is regarded as simply supported beam located vertical plane subjected non-uniform axial lateral forces. solved by finite element method. effects of outside diameter, top tension ratio, sea surface current velocity, drag force coefficient, floating system drift distance water depth on displacement discussed. Results show...
Use of aluminum alloys for automotive applications is growing steadily. However, galvanic corrosion a major concern with those alloys. Because the predominate use steels in industry, majority accelerated test procedures commonly accepted by industry are designed cosmetic and perforation steels. Adopting such tests without fundamental understanding process may produce misleading results. Electrochemical studies were conducted to examine acceleration effects several parameters on different...
In order to analyse the natural vibration frequencies and mode shapes of deep sea top tensioned riser, an analysis model is established in present study. The effect in-line bending displacement on riser considered model. finite element method adopted this paper calculate riser. top-tension force current velocity has discussed Results show that frequency direction higher than cross-flow are not standard sinusoidal curve. different from direction. Moreover, change surface a great influence shapes.
An understanding of water exchange processes is essential for assessing quality management issues in coastal bays. This paper evaluates the impact on pollution persistence a macro-tidal semi-closed bay through two transport time scales (TTS), namely residence and exposure time. The numerical model was calibrated against field-measured data various tidal conditions. Simulated current speeds directions were shown to agree well with field data. By considering different release scenarios...
In this paper, considering combined excitations of the steady current, surface wave, internal solitary wave as well as, vessel’s surge and heave motions, a time‐domain model is established to investigate lateral dynamic response marine drilling risers. The finite element Newmark‐ β methods are used solve nonlinear partial differential equation in time‐domain. entire numerical solution process realized by self‐developed program based on MATLAB. reliability verified comparing it with published...
Abstract The corrosion potential of AISI type 316 stainless steel and the rate oxygen reduction, as measured by cathodic polarization curve, have been determined with without formation a natural marine bacterial film on surface. data show that amount scatter in increases dramatically presence biofilm spotty nature encourages pit initiation. Several possible mechanisms for effect are discussed.
