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.

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.

Mesh-free hydrodynamic stability
Journal of Computational Physics, 2023 A specialized mesh-free radial basis function-based finite difference (RBF-FD) discretization is used to solve the large eigenvalue problems arising in hydrodynamic stability analyses of flows in complex domains. Polyharmonic spline functions with polynomial augmentation (PHS+poly) are used to construct the discrete linearized incompressible and ...

Bounds on transport from hydrodynamic stability
Physics Letters B, 2023 It was recently shown that the dispersion relations describing singularities of retarded two-point functions in causal quantum field theories always satisfy the fundamental inequality Imω≤|Imk|, and that several rigorous bounds on transport coefficients ...

Calculation of strength of stilling basins and pressure in downstream water outlet structures [PDF]
E3S Web of Conferences, 2023 Calculations performed to determine the strength of the stilling basin and apron of the downstream zone should mainly be carried out, considering the conditions of their stability and strength.

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 ...
