“…The hybrid RANS/LES method presented in this paper is general and can be used for resistance optimization studies of any underwater vessel. Further, the method can also be utilized to study pressure distributions in shells which can be important in acoustic problems, e.g., Zarastvand et al [19] and Asadijafari et al [20].…”

The Subsea Shuttle Tanker (SST) was proposed by Equinor as an alternative to subsea pipelines and surface tankers for the transportation of liquid carbon dioxide (CO2) from existing offshore/land facilities to marginal subsea fields. In contrast to highly weather-dependent surface tanker operations, the SST can operate in any condition underwater. Low resistance is paramount to achieving maximum range. In this paper, the resistance of the SST at an operating forward speed of 6 knots (3.09 m/s) and subject to an incoming current velocity of 1 m/s is computed using Computational Fluid Dynamics (CFD). The Delayed Detached Eddy Simulation (DDES) method is used. This method combines features of Reynolds-Averaged Navier–Stokes Simulation (RANS) in the attached boundary layer parts at the near-wall regions, and Large Eddy Simulation (LES) at the unsteady, separated regions near to the propeller. The force required to overcome forward resistance is calculated to be 222 kN and agrees well with experimental measurements available in the open literature. The corresponding power consumption is calculated to be 927 kW, highlighting the high efficiency of the SST. The method presented in this paper is general and can be used for resistance optimization studies of any underwater vessel.

“…In this regard, it is worth noting that the authors of this approach are praised as researches who developed two review studies for the first time through the STL of the various kinds of shell and plate constructions and presented all of the papers in this filed [26, 27]. Unlike the last publications, a new review paper is organized in this approach to study only the acoustic characteristics of the multilayered plate constructions.…”

This study collects all of the existent papers in the field of acoustic transmission across multilayered plate constructions. Herewith, a comprehensive source is proposed wherein approximately 410 references are reviewed and described from the first [Formula: see text] to [Formula: see text]. In the first part, in addition to the presentation of a complete explanation about the importance of the acoustic analysis of these structures, appropriate formulations are also provided. Furthermore, an overview of the thematic correspondent is carried out. Since the type of material used in these constructions can be very important in sound insulation, the significance of this subject is remarked. The papers are then classified based on their acoustic excitation fields containing plane wave, diffuse, random, and point source. After analyzing the research approaches according to different environmental properties, the articles are ordered based on their boundaries as finite and infinite. To present reliable outcomes, it is necessary to investigate a proper theory proportional to the structure’s thickness. Herewith, this issue is also discussed in detail. The review is also expanded to focus on the different vibroacoustic solutions. Before concluding remarks, the authors' research works are presented wherein either optimization algorithms or control techniques improve the acoustic performance of these structures.

“…Laminated composite structures are widely used in aircraft engine shroud and wing spoiler, solid rocket motor casing, missile launcher canister due to its high specific strength, high specific modulus, superior shock absorption, fatigue resistance, and simple manufacture technology [1][2][3]. Thus, research on the acoustic characteristics of sandwich or interface of composite structures has always been the focus of attention, which is used to design the materials and properties of interface layer [4,5].…”

An air-coupled ultrasonic technology is introduced as a new tool for evaluating the interfacial quality of bonded structures in this paper. Thus, a mathematical model including the stiffness coefficient, the transmission coefficient and the frequency, etc. is proposed. Two type resonant frequencies, namely, the first type resonance frequency (RFⅠ) and the second type resonance frequency (RFⅡ), have been obtained by numerical solving the model. The interval of the RFⅠ is related to the thickness of a polymethyl methacrylate (PMMA) layer. Similarly, the interval of the RFⅡ depends on the thickness of an aluminum (Al) layer. In addition, the stiffness coefficient is associated with the RFⅠ but not with the RFⅡ. The RFⅠ drifts to high-frequency with different speed from the low stiffness coefficient to the high stiffness coefficient, which no longer changes when the stiffness coefficient tends to infinity. The before-RFⅠ moves faster than after-RFⅠ in a "Period" of the RFⅡ. With the increase of the stiffness coefficient, the transmission coefficient gradually increases, and then increases slowly when the stiffness coefficient approaches to a critical value. Several double-layer bonded samples with the different thicknesses were made to carry out air-coupled ultrasonic experiment. The change of stiffness coefficients was simulated by different bonding time. Transmission signals from ultrasonic testing were recorded for further processing. Comparing the experimental and simulation results, the stiffness coefficient of the bonded structure can be judged by the RFⅠ and the transmission coefficient.
