DIAM – A Matrix Tool for Pump Vibrations

| 2024:1051 | Rainer Normann Tu Darmstadt
In this research project a DIAM-Matrix tool together with a flow chart has been developed for the problem of pump vibrations.

\u003Cp\u003EIn the 3 matrices M1, M2, and M3 a total of 40 different Vibration Phenomena have been defined in the rows of these matrices versus 29 different Detections in matrix M1, 27 different Investigations in matrix M2 and 30 different Analysis methods in matrix M3, presented in the columns of the matrices. The Vibration Identification starts with Detections and continues with Investigations and Analysis Methods. If one or even more Vibration Phenomena have been identified, the procedure continues with the Vibration Mitigation in Matrix M4, in which 29 Mitigation possibilities are related to the 40 Vibration Phenomena.\u003C/p\u003E

    Cavitation induced vibrations in orifice plates and a partially closed valve

    This study aims to experimentally investigate flow-induced vibrations and cavitation in single-hole and multi-hole orifices and a partially closed Stafsjö valve. The goal is to provide experimental data for validating Computational Fluid Dynamics (CFD) models.
