The estimation of fluid flows inside a centrifugal pump in realtime is a challenging task that cannot be achieved with long-established methods like CFD due to their computational demands. We use a projection-based reduced order model (ROM) instead. Based on this ROM, a realtime observer can be devised that estimates the temporally and spatially re...

Realtime reconstruction of flow fields is a prerequisite to precise condition monitoring of hydraulic plant components. Because models based on Navier-Stokes equations are usually too complex for a realtime use, reduced order models (ROMs) are a viable alternative. Specifically, ROMs based on proper orthogonal decomposition and Galerkin projection...
