Numerical Study on the Hydrodynamic Characteristics of Submarine Pipelines under the Impact of Real-World Tsunami-Like Waves

Abstract: Submarine pipelines have been extensively used for marine oil and gas extraction due to their high efficiency, safety, and low price. However, submarine pipelines are vulnerable to extreme waves (i.e., tsunami waves). Previous research has often used solitary waves as a basis for studying the impacts of tsunami waves on submarine pipelines, although the hydrodynamic characteristics and wave properties drastically differ from those of real-world tsunami waves. This paper numerically investigates the hydrodynami… Show more

“…where H is the wave height; k is the effective number; x o is the wave peak location at initial time t; C is the wave speed. Depending on N-waves theory, the tsunami-like wave is numerically generated using a combination of three solitary sech 2 ( * ) wave profiles [16]- [21]. And the combination wave can be expressed as…”

“…In this model, the renormalization-group (RNG) k-ε turbulence model was implemented as the turbulence closure, which has been successfully employed to investigate the turbulence field around the structure and the whole computational domain under the interaction between structure and water [29,30]. The volume of fluid (VOF) method was used to capture the interface between the air and water [31][32][33], and the pressure and velocity was coupled by the generalized minimal residual methods (GMRES) pressure-velocity solvers. In the free surface flow, the mass and momentum conservation equations in the flow can be expressed as…”

“…The effects of gap-to-diameter ratios were investigated in this study. Zhao et al [22] presented a two-dimensional numerical study on the hydrodynamics of submarine pipelines. The effects of wave height, water depth, and pipeline diameter on the hydrodynamic characteristics of submarine pipelines were investigated by using a real-world tsunami wave and a solitary wave.…”
