Study of unsteady phenomena in pump as turbine
Hliboký, Samuel ; Zemanová, Lucie (oponent) ; Štefan, David (vedoucí práce)
This diploma thesis deals with centrifugal pump running as a turbine. Basic working principles of a pump are included, both in pump and turbine regime. Experimental data obtained from laboratory test bed are compared with CFD simulation on slightly simplified geometry. Obtained results are then processed using spectrogram. Influence of time step and mesh size on results is also researched.
