Abstract: Pipe bends are commonly used in piping systems in offshore and subsea installations. The present study explores the design considerations for the honeycomb straightener inserted downstream of a 90-degree pipe bend. The ...

Abstract: Flow-induced vibration (FIV) is a common phenomenon in ocean engineering for subsea structures with circular-shaped cross sections. A large amount of computational resources or experimental efforts are required to predict ...

Abstract: The objective of the present study is estimating hydrodynamic forces acting on cylinders undergoing vortexinduced vibration (VIV) using dynamic mode decomposition (DMD). The cylinders are subjected to a uniform incoming ...

Abstract: This work investigates the hydrodynamic performance of a subsea shuttle, an extra-large freight submarine, during near-seabed operation. The three-dimensional Reynolds-averaged Navier–Stokes method combined with the k − ω ...

Abstract: The turbulent flow through a 90-deg circular pipe bend is investigated by carrying out the numerical simulations using the Reynolds-averaged Navier–Stokes (RANS) turbulence model in the present study. The objective of the ...

Abstract: The dynamic mode decomposition (DMD) and proper orthogonal decomposition (POD) are used to analyze the coherent structures of turbulent flow around vibrating isolated and piggyback cylinders configurations subjected to a ...
