This paper deals with numerical simulation of airflow-rivulet interaction using fluid-structure interaction (FSI). Computational fluid dynamics (CFD) model involves uniform flow which represents air with constant speed at inlet. An incompressible fluid flow with Navier-Stokes equations has been applied. Computational structure dynamics (CSD) model involves cylinder and rigid water rivulet which is allowed to move on cylinder's surface. Periodic movement of rivulet has been observed which vibration frequency has been lower than vortex shedding frequency. The frequency of periodically moving rivulet also has appeared in estimated cylinder aerodynamic characteristics.
