Stretching dynamics of polymers in microfluidics is of particular interest of polymer science. Applying a mechanical, electrical or hydrodynamical force on a long polymer deforms the relaxed configuration of the polymer. According to this effect a polyelectrolyte can be deformed from its coiled equilibrium configuration to an extended chain by application of uniform (for an anchored polymer) or non-uniform (for a freely moving polymer) electric field. By the mean of hybrid LB-MD  multi scale simulations we investigate the contribution of the hydrodanamics in compare to the electrostatics in the polymers stretching.  As an application we discuss the results of this research in translocations through nano pores, when the driving force is an external electric field.
