Effect of Rotation on Marangoni Convection in a Relatively Hotter or Cooler Liquid Layer

A. K. Gupta , D. Surya

The effect of Coriolis force on the onset of surface tension driven convection in a relatively hotter or cooler liquid layer confined between two horizontal boundaries in the presence of uniform rotation is considered theoretically. The modified linear stability analysis is performed to obtain the eigenvalue system of eighth order. A Fourier series method is used to obtain the characteristic value equation analytically for the Marangoni number M which is then computed numerically. It is established that the rotation has stabilizing character irrespective of whether the liquid layer is relatively hotter or cooler.
