Abstract
Double diffusive (DD) convection is a phenomenon
frequently observed in the oceans and in many
industrial situations (Govindarajan and Sahu, 2014).
The “double-diffusive flow” means the flow in the
presence of two species, which are diffusing at
different rates. In this review, the instabilities that
arise due to the double-diffusive effects in conditions
which are supposed to be stable, according to our
intuition, are discussed. The review is restricted to
viscosity-stratified flows in two configurations,
namely, core-annular/three-layer, and displacement
flows. It is to be noted that the DD phenomena in
density-stratified systems have been very well studied
in the literature (see for example Turner, 1974), and
this is not the subject of this review. However, a brief
overview of double-diffusive phenomena in density
stratified systems is given below, which will help us
in understanding the underlying physics i n t he present
systems
