Summary
This summary is machine-generated.

We investigated bubble and spike motion in Richtmyer-Meshkov instability. A key finding reveals that the physically relevant bubble solution exhibits a flattened surface, not finite curvature.

Area of Science:

  • Fluid dynamics
  • Plasma physics
  • Astrophysical phenomena

Background:

  • The Richtmyer-Meshkov instability (RMI) is crucial for understanding turbulent mixing in various physical systems.
  • Previous studies often focused on 2D models or specific bubble shapes.
  • Coherent structures in RMI are complex and require detailed analysis.

Purpose of the Study:

  • To analyze the coherent motion of bubbles and spikes in RMI.
  • To derive and characterize regular asymptotic solutions for bubble dynamics.
  • To identify physically significant solutions and their properties.

Main Methods:

  • Analysis of equations governing local bubble dynamics.
  • Derivation of asymptotic solutions parametrized by principal curvature.
  • Investigation of isotropic 3D and 2D periodic flows.

Main Results:

  • A family of regular asymptotic solutions for bubble dynamics was identified.
  • The physically significant solution corresponds to a bubble with a flattened surface.
  • The evolution of the bubble front was described, and diagnostic parameters were suggested.

Conclusions:

  • The study provides a new perspective on bubble morphology in RMI.
  • Flattened bubble surfaces are key to understanding RMI evolution.
  • The findings offer valuable insights for simulations and experimental diagnostics.
