Abstract

Modified double-diffusive convection in viscoelastic fluid of the Veronis’ and Stern’s type configurations is considered in the present paper. Semi-circle theorems that prescribe upper limits for the complex growth rate of oscillatory motions of neutral or growing amplitude are derived. The limits so derived naturally culminate in sufficient conditions which precludes the non-existence of such motions. The results obtained herein significantly improve upon the earlier results derived in this direction.Cite this ArticleHari Mohan, Pardeep Kumar, Sada Ram.Modified Double-Diffusive Convectionin Viscoelastic Fluid.
