The centrifugal pump is especially designed to work on the same shaft as the corresponding ORC microturbine. The ORC unit works on R7100 (HFE7100) – a lowboiling fluid characterized by a zero ozone depletion potential coefficient. The pump has the following rated parameters: nominal flow rate of working fluid 4 kg/s, operating rotor speed 10 000 rpm. The pump designed by means of the 0D meanline method is subject to computational fluid dynamics (CFD) calculations and analysis. The obtained flow field results are discussed and performance characteristics of the pump are presented. The non-cavitating operational region is determined for the pump.}, type={Article}, title={Design and performance analysis of ORC centrifugal pumps}, URL={http://journals.pan.pl/Content/118782/PDF/art09.pdf}, doi={10.24425/ather.2020.135860}, keywords={CFD, ORC power plant, Microturbine and pump, 0D meanline design}, }
