Abstract
The purpose of this work is to design and determine the performance of a prototype centrifugal pump impeller for an organic Rankine cycle (ORC) power plant of maximum power 100 kW. 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.
期刊介绍：
The aim of the Archives of Thermodynamics is to disseminate knowledge between scientists and engineers interested in thermodynamics and heat transfer and to provide a forum for original research conducted in Central and Eastern Europe, as well as all over the world. The journal encompass all aspect of the field, ranging from classical thermodynamics, through conduction heat transfer to thermodynamic aspects of multiphase flow. Both theoretical and applied contributions are welcome. Only original papers written in English are consider for publication.
