Double-diffusive rotatory convection coupled with c ross-diffusions in viscoelastic fluid

The present paper investigates the effect of a unif orm vertical rotation on the physical problem of do uble-diffusive convection coupled with cross-diffusions in viscoel astic fluid. Some general qualitative results conce rning the stability of oscillatory motions and limitations on the oscillatory motions of growing amplitude are d erived. The results for the double- diffusive convection proble ms with or without the individual consideration of Dufour and Soret effects follow as a consequence.
