Modeling and simulation of a single-mode multiphase Richtmyer–Meshkov instability with a large Stokes number

AIP Advances, 2019
This study focuses on the effects of a large Stokes number (St) on the perturbation growth in linear and nonlinear stages of a Richtmyer–Meshkov instability (RMI) in a gas-particle system, which to the best of our knowledge has not been previously ...

Parametrically Excited Surface Waves: Two-Frequency Forcing, Normal Form Symmetries, and Pattern Selection [PDF]

, 1998
Motivated by experimental observations of exotic standing wave patterns in the two-frequency Faraday experiment, we investigate the role of normal form symmetries in the pattern selection problem.

Numerical Analysis of Roll Hydrodynamic Coefficients of 2D Triangular Cylinder Using OpenFOAM

Journal of Marine Science and Engineering
Predicting the roll damping coefficient of a ship is a crucial factor in determining the dynamic stability of the vessel. However, a nonlinear analysis that considers the viscosity of the fluid is required to accurately estimate the roll damping ...

An Efficient Diving Control Scheme for Autonomous Underwater Vehicle Experiencing Actuator Failure: A Multi-Layer Cubature Kalman Filter-Based Nonlinear Model Predictive Control Approach

IEEE Access
Autonomous underwater vehicles (AUVs) are primarily capable of withstanding prolonged periods in unstructured marine environments. These are subject to several uncertainties, including the effects of underwater currents or drift, topography, water ...

NMPC-Based 3D Path Tracking of a Bioinspired Foot-Wing Amphibious Robot

Journal of Marine Science and Engineering
To achieve accurate 3D path tracking of a foot-wing hybrid-driven amphibious biomimetic robot under periodically varying forces, this study analyzes the periodic propulsion forces generated by the flapping motion of the robot’s feet and wings, along with

Holographic Path to the Turbulent Side of Gravity

Physical Review X, 2014
We study the dynamics of a 2+1-dimensional relativistic viscous conformal fluid in Minkowski spacetime. Such fluid solutions arise as duals, under the “gravity/fluid correspondence,” to 3+1-dimensional asymptotically anti–de Sitter (AAdS) black-brane ...
