摘要

设计了一种轴流式风机，用于 CSP 电站 sCO2 布莱顿循环的干式冷却，并在 ISO 5801:2017 A 型风机测试设备中制造和实验测试了该风机的比例模型。虽然设计程序对设计流速下总静态效率的估算相对较高，达到 74.4%，但实验发现风机效率仅为 50.6%。本文采用实验和数值方法详细调查了风扇性能下降的原因。调查发现，测试风扇的轮毂配置、叶尖间隙大小和规模是性能下降的原因。本文确定了两种可供选择的轮毂和外壳配置，可显著提高风扇的性能。

Investigation into the predicted performance of a cooling fan for an sCO2 concentrated solar power plant

An axial flow fan is designed for dry cooling of a sCO2 Brayton cycle for a CSP plant, and a scaled model of the fan is manufactured and tested experimentally in an ISO 5801:2017 Type A fan test facility. While the design procedure’s estimate of the total-to-static efficiency at the design flow rate is relatively high, at 74.4%, the experimental fan efficiency was found to be only 50.6%. This paper details an investigation into the causes of fan performance degradation, using both experimental and numerical methods. The investigation finds that the hub configuration, tip clearance size, and scale of the test fan is responsible for the reduced performance. Two alternative hub and casing configurations are identified which improve the fan’s performance significantly.
