RT Journal Article T1 Arrow-shaped elasto-inertial rotating waves. A1 López-Alonso, José Manuel A1 Altmeyer, Sebastian K1 Dinámica de fluidos K1 Viscoelasticidad AB We present direct numerical simulations of the Taylor–Couette flow of a dilute polymer solution when onlythe inner cylinder rotates and the curvature of thesystem is moderate (η = 0.77). The finitely extensiblenonlinear elastic-Peterlin (FENE-P) closure is usedto model the polymer dynamics. The simulationshave revealed the existence of a novel elastoinertialrotating wave characterized by arrow-shapedstructures of the polymer stretch field aligned withthe streamwise direction. This rotating wave pattern iscomprehensively characterized, including an analysisof its dependence on the dimensionless Reynoldsand Weissenberg numbers. Other flow states havingarrow-shaped structures coexisting with other typesof structures have also been identified for the first timein this study and are briefly discussed.
