PSEUDOSOUND PRESSURE OSCILLATIONS CAUSED BY THE INTERACTION OF A FLUID FLOW WITH THE OBSTACLE IN THE FORM OF A CIRCULAR CYLINDER IN A PIPE

A simulation of the vibroacoustic processes proceeding in a long pipe with an obstacle in the form of a circular cylinder, in which a fl uid fl ows, has been performed with regard for the action of the vortices formed downstream of the cylinder on the dynamics of the system. On the basis of the computational procedure developed, the vibroacoustic characteristics of the system have been determined. The distributions of the gasdynamic parameters of the fl uid fl ow in the pipe and the vibroacoustic behavior of the system are discussed
