The concentric elongational flow known as a bicomponent coextrusion fiber spinning process was experimentally examined. In this study, a Newtonian fluid and aqueous solutions of polyacrylamide(PAA) were used for a skin and core layer, respectively. In the observation of concentric flow, the interface between core and skin layers varied linearly along the flow direction. In the numerical simulation using the Giesekus model, it was shown that the shape of interface was dependent on a ratio of flow rate between two fluids.
