  • CFD analysis of the dynamic behaviour of a pipe system
    Sekavčnik, Mihael ; Ogorevc, Tine ; Škerget, Leopold
    An unsteady flow of viscous-compressible fluid through a pipe system induced by a transient disturbance at the pipe intake is studied by means of ANSYS-CFXNavier-Stokes code. The disturbance is ... predefined as a time-dependent boundary condition at the pipe inlet. The flow through the pipe is calculated using a system of RANS equations combined with various turbulence models. Based on data obtained by analysing a single straight, circular pipe, advanced systems of three and seven pipes are modeled and systematically analysed. The pressure responses of complex, periodically excited systems are observed under various boundary conditions. Time-domain results are transformed into the frequency-domain in order to determine the frequency content of the dynamic response for each simulation. Considering relevant criteria, an approach is presented for the determination of crucial parameters to enable the evaluation of system operation. An original diagram of such parameters is proposed, which allows convenient evaluation of the performance of various pipe systems.
