Thwarting Marangoni instability in a viscoelastic liquid film via parametric forcing
The suppression of Marangoni-driven instability in a heated viscoelastic thin film was investigated under parametric forcing. It was found that, unlike Newtonian systems which exhibit a single-frequency stabilization threshold, an island of stability bounded by two critical frequencies emerges due to fluid elasticity. Stabilization and destabilization were both shown to result from the memory effects imparted by elasticity. A fundamental shift in the conditions for instability suppression was thereby revealed.
