Transport and tumbling of polymers in viscoelastic shear flow
Sadhana Singh, R. K. Singh, Sanjay Kumar
Polymers in shear flow are ubiquitous and we study their motion in a viscoelastic fluid under shear. Employing dumbbells as representative, we find that the center of mass motion f…

Dynamics of a polymer under multi-gradient fields
Sadhana Singh, Sanjay Kumar
Effects of multi-gradient fields on the transport of a polymer chain have been investigated by using generalized Langevin dynamics simulations. We observe that the natural frequenc…
