  Modified Double-Diffusive Convection in Viscoelastic Fluid

  By Hari Mohan, Pardeep Kumar, Sada Ram

  Abstract: Normal 0 false false false EN-IN X-NONE X-NONE MicrosoftInternetExplorer4 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 …

  On Triply-Diffusive Convection in Completely Confined Fluids

  By Sada Ram

  Abstract: The present paper derives some energy relationships and limitations for the growth rate of a disturbance in the problems of triply-diffusive convection of Veronis type configurations for fluids completely confined in an arbitrary region in the three dimensional Euclidean space 3 R .Keywords: Triply-diffusive convection, Rayleigh numbers, Prandtl numbers, Lewis numbers
