An Overset Grid Method for Fluid-Structure Interaction

World Journal of Mechanics, 2014
An overset grid methodology is developed for the fully coupled analysis of fluid-structure interaction (FSI) problems. The overset grid approach alleviates some of the computational geometry difficulties traditionally associated with Arbitrary-Lagrangian-Eulerian (ALE) based, moving mesh methods for FSI.

Direct numerical simulation of particulate flows with an overset grid method

Journal of Computational Physics, 2017
We evaluate an efficient overset grid method for two-dimensional and three-dimensional particulate flows for small numbers of particles at finite Reynolds number. The rigid particles are discretised using moving overset grids overlaid on a Cartesian background grid.

Numerical Simulation of Ship Maneuvers through Self-Propulsion

Journal of Marine Science and Engineering, 2021
The typical maneuvering of a ship can reflect its maneuvering characteristics, which are closely related to the safety and economy of its navigation. The accurate prediction of a ship’s maneuvering characteristics is essential for its preliminary design.

Local Inverse Mapping Implicit Hole-Cutting Method for Structured Cartesian Overset Grid Assembly

Entropy, 2023
An automatic hole-cutting method is proposed to search donor cells between a structured Cartesian mesh and an overlapping body-fitted mesh. The main flow is simulated on the structured Cartesian mesh and the viscous flow near the solid boundary is ...

Investigation of Aeroelasticity Effect on Missile Separation from the Internal Bay

International Journal of Aerospace Engineering, 2023
There is a strong aerodynamic interference when launching the missile in the embedded mode. During the separation process, the carrier aircraft safety may be threatened due to large slenderness ratio, low structural stiffness, and aeroelasticity effects ...

Application of an overset grid method for the performance analysis of flapping airfoils

Journal of Physics: Conference Series, 2022
Abstract With the growing importance of renewable energy, the interest in energy-harvesting technologies based on flow-induced vibrations of airfoils has been rekindled in the past few years. Compared to conventional turbines, these devices are centrifugal stress-free and hence they are structurally more robust.
