Novicos is developing a vibroacoustic measurement concept for determining flow velocity in a research project. Turbulence or particles inside the flow amplify the excitations on the pipelines and produce disturbances that influence the accuracy of the measurement results. By determining and quantifying these disturbances, we create the vibroacoustic background as a basis for the development project. The goal is a conservative estimation of the strongest, excitatory effects as well as the maximum sources that can be expected. For this purpose, the structure-borne sound excitation by flow and particle collisions was simulated.
