Numerical Analysis of Submarine Hydrodynamic Force Near the Seabed

Kapal, 2023
One of the aspects that need to be considered in designing a submarine is the effect of the hydrodynamic aspect on resistance and maneuverability in various operating conditions. In certain conditions, submarines operate in conditions near the seabed. In

Numerical Simulation of Cavitation and Damping Force Characteristics for a High-Speed Supercavitation Vehicle

Journal of Marine Science and Engineering, 2021
In this study, an attempt has been made to investigate the supercavitation and hydrodynamic characteristics of high-speed vehicles. A homogeneous equilibrium flow model and a Schnerr–Sauer model based on the Reynolds-averaged Navier–Stokes method are ...

Optimal Lowest Astronomical Tide Estimation Using Maximum Likelihood Estimator with Multiple Ocean Models Hybridization

ISPRS International Journal of Geo-Information, 2020
Developing an accurate Lowest Astronomical Tide (LAT) in a continuous form is essential for many maritime applications as it can be employed to develop an accurate continuous vertical control datum for hydrographic surveys applications and to produce ...

(Non)-dissipative hydrodynamics on embedded surfaces [PDF]

Journal of High Energy Physics, 2014
We construct the theory of dissipative hydrodynamics of uncharged fluids living on embedded space-time surfaces to first order in a derivative expansion in the case of codimension-1 surfaces (including fluid membranes) and the theory of non-dissipative hydrodynamics to second order in a derivative expansion in the case of codimension higher than one ...

Modelling of the coupling hydrodynamic transfer for a gas-liquid countercurrent flow on a wavy surface [PDF]

, 2003
This paper concerns laminar countercurrent gas–liquid flow over a wavy wall column, in the case of a falling liquid film. The modelling concerns the coupling of hydrodynamic and heat and mass transfer for an absorption as an example of application.

Hydrodynamics and surface properties influence biofilm proliferation

Advances in Colloid and Interface Science, 2021
A biofilm is an interface-associated colloidal dispersion of bacterial cells and excreted polymers in which microorganisms find protection from their environment. Successful colonization of a surface by a bacterial community is typically a detriment to human health and property.

Prediction of Unstable Hydrodynamic Forces on Submerged Structures under the Water Surface Using a Data-Driven Modeling Approach

Buildings, 2022
Catastrophic failures of partially or fully submerged structures, e.g., offshore platforms, hydrokinetic turbine blades, bridge decks, etc., due to the dynamic impact of free surface flows such as waves or floods have revealed the need to evaluate their ...
