Structure and Branching of Unstable Modes in a Swirling Flow
Mathematics, 2021 Swirling has a significant effect on the main characteristics of flow and can lead to its fundamental restructuring. On the flow axis, a stagnation point with zero velocity is possible, behind which a return flow zone is formed.

Stability and error analysis of IMEX SAV schemes for the magneto-hydrodynamic equations [PDF]
SIAM Journal on Numerical Analysis, 2021 We construct and analyze first- and second-order implicit-explicit (IMEX) schemes based on the scalar auxiliary variable (SAV) approach for the magneto-hydrodynamic equations.

Supersonic gas jet stabilization in laser–plasma acceleration
High Power Laser Science and Engineering, 2023 Supersonic gas jets generated via a conical nozzle are widely applied in the laser wakefield acceleration of electrons. The stability of the gas jet is critical to the electron injection and the reproducibility of the wakefield acceleration.

The Stability of a Hydrodynamic Bravais Lattice
Symmetry, 2022 We present the results of a theoretical investigation of the stability and collective vibrations of a two-dimensional hydrodynamic lattice comprised of millimetric droplets bouncing on the surface of a vibrating liquid bath. We derive the linearized equations of motion describing the dynamics of a generic Bravais lattice, as encompasses all possible ...

International Journal of Naval Architecture and Ocean Engineering, 2021 In this study, hull dimensions of an FPSO were optimized to maximize its operability at Brazil field. In contrast with the previous works which have used simplified models to evaluate some indicators related to stability and hydrodynamic performances of ...
