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.

ORC离心泵的设计与性能分析

本工作的目的是设计和确定最大功率为100kw的有机朗肯循环(ORC)电厂的原型离心泵叶轮的性能。离心泵是专门设计为在同一轴上工作，作为相应的ORC微型涡轮机。ORC装置在R7100 (HFE7100)上工作，这是一种低沸点流体，其特点是臭氧消耗潜在系数为零。该泵的额定参数如下:工作流体公称流量4kg /s，运行转子转速10000rpm。采用0D平均线法设计的泵需要进行计算流体动力学(CFD)的计算和分析。对所得流场结果进行了讨论，并介绍了泵的性能特点。确定泵的无空化操作区域。
