Originální abstrakt
Large amplitude vibrations of cylindrical structural elements are observed when under the simultaneous action of wind and rain. Due to the action of wind and rain a translating water rivulet forms on the skew cable surface changing significantly the aerodynamic properties of the cable. General mathematic description of the problem is in the form of nonlinear equations, thus this problem is frequently simplified to 1 or 2 degree of freedom system. Another possibility of avoiding complex mathematic description is numerical simulation of the problem using CFD computer program. The paper describes the fundamental principles of modeling rain-wind flow interacting with an obstacle.
