In this lecture, we first review modeling and simulation that have been carried out in the last two decades for nonlinear inviscid and viscous Newtonian rotating jet flows with curved centerlines. Next, we consider the governing modeling system, which we developed recently, for the polymeric fiber jets and calculate the corresponding nonlinear solutions for quantities such as jet speed, radius, stretching rate, trajectory and strain rate versus different values of the arc length and parameters that can represent effects due to rotation, friction, surface tension and relaxation time. We present the application of such results in force spinning process, which is a relatively new technology that uses centrifugal force due to the externally imposed rotational forces to produce nanofibers from different materials with important technological applications.
