Review on convection phenomenons in evaporative , non-evaporative fluids and polymer solutions

Convective motions and cellular planform formation in fluid are important issues in physical-chemical hydrodynamic, mass and heat transfer in shallow fluid layer systems with free surface. Because of their special importance in the manufacture of thin films in diverse industries such as paints, adhesive, membranes and solar cells, recognition of these kind of motions in polymer solutions have been the focus of many investigations. Generally, this review deals with convection phenomenon in non-evaporative/evaporative, single/multi componant systems, related theories and mechanisms. The main conclusion to be drawn is that Thermal-Marangoni Bestehorn and Solutal- Marangoni numbers are significant to understand and predict convection phenomena in evaporative solutions.
