Abstract
In the literature, the shift of the spinodal line of polymer solutions under Bow is attributed either to an actual shift of the spinodal due to a nonequilibrium modification of the equation of state for the che mical potential, or to an apparent shift due to an increase of hydrody namic fluctuations owing to the flow. Here we see that both approaches are compatible and that both effects add up.
