In this work, we explore how non-equilibrated polymer systems evolve as they flow side by side within a microchannel. As the system is evolving and the two polymer solutions are interacting, strong enough gradient in tension can create Marangoni flows transverse to the channel flow, resulting in a 3 dimensional flow evolution.
