Summary

Experiments show that increasing magnetic fields suppress the wavelength of Rayleigh-Taylor instability between two liquids. The growth rate of interface deformation increases with the applied magnetic field.

Area of Science:

  • Fluid dynamics
  • Magnetohydrodynamics
  • Instability phenomena

Background:

  • The Rayleigh-Taylor instability occurs at the interface of two fluids of different densities when accelerated.
  • Magnetic fields can influence fluid behavior, particularly in ferrofluids.

Purpose of the Study:

  • To investigate the effect of an external magnetic field on Rayleigh-Taylor instability.
  • To measure the wavelength and growth rate of the instability under varying magnetic fields.

Main Methods:

  • Confining a dense magnetic liquid and a less dense immiscible liquid in a Hele-Shaw cell.
  • Applying a magnetic field perpendicular to the Hele-Shaw cell.
  • Measuring instability wavelength and growth rate as a function of magnetic field strength.

Main Results:

  • The wavelength of the Rayleigh-Taylor instability decreases with increasing magnetic field.
  • The growth rate of the interface deformation increases with the magnetic field.
  • Interface amplitude grows exponentially in the early stage.

Conclusions:

  • The study provides experimental data on magnetic field effects on Rayleigh-Taylor instability.
  • Results are compared with theoretical predictions from linear stability analysis.
