This study analyzes fluid interface stability under shear flow, generalizing prior research for astrophysical applications. We incorporated surface tension and compressibility to understand mixing dynamics in space.

Area of Science:

  • Fluid dynamics
  • Astrophysics
  • Plasma physics

Background:

  • Shear flows can destabilize fluid interfaces, leading to mixing.
  • Astrophysical systems often involve interfaces between fluids with different densities.
  • Understanding interface stability is crucial for modeling astrophysical phenomena.

Purpose of the Study:

  • To generalize the linear stability analysis of fluid interfaces under shear flow.
  • To incorporate arbitrary Atwood numbers, surface tension, and weak compressibility.
  • To provide insights into mixing processes in astrophysical systems.

Main Methods:

  • Linear stability analysis.
  • Mathematical modeling of fluid interfaces.
  • Perturbation theory.
