Thermal instability in a viscoelastic fluid in hydromagnetics

  • R. C. Sharma


The stability of a layer of Oldroyd fluid heated from below and subject to a magnetic field is considered. The magnetic field is found to have a stabilizing influence. The analytic conditions for nonexistence of overstability are investigated.
