This paper presents the result of design optimization for three-bladed pump inducer using a three-dimensional inverse design approach, Computational Fluid Dynamics (CFD) and Design of Experiment (DoE) taking suction performance and cavitation instability into consideration.
ADT is one of ALPHEUS project partner: a €5m project funded by the European Union’s Horizon 2020 program. It will improve reversible pump/turbine (RPT) technology and adjacent civil structures needed to make pumped hydro storage economically viable in shallow seas and coastal environments with flat topography.
This paper presents the results of the development of a cryogenic pump, consisting of inducer, impeller and diffuser, for Liquefied Natural Gas (LNG) transfer and pressurization. The newly designed pump was tested by using water test tunnel and showed good suction performance.
The customer, one of the world’s largest pump manufacturers, asked ADT to design an inducer to fit in one of their products, a multi-stage centrifugal pump. A designer needs to consider the suction performance of the first stage to make sure that the pump can sustain low inlet pressure without suffering of cavitation and therefore pressure drops vibration and damage.
