摘要

合理设计离心泵可以减少功率损失,提高效率。本研究旨在探讨和分析不同蜗壳集热器配置对离心泵性能的影响。使用熵产生率检测损失的位置,而使用用户定义代码评估损失的数量。根据与标准管道的连接选择三个蜗壳集热器。通过定常流数值分析,确定了离心泵的性能参数,选择了改进的蜗壳集热器设计方案。通过对基础型和改进型蜗壳集热器的实验对比,验证了蜗壳集热器的合理设计有助于减少后续位置的二次流损失,从而降低了熵产和损失。与基础泵相比,改进的蜗壳集热器在占空流量下将泵效率提高了3%。

Effect of Volute Collector on the Performance of Centrifugal Pump Based on Entropy Generation Analysis
A proper design of centrifugal pumps reduces power loss and improves efficiency. This study aims to investigate and analyze the effect of different volute collector configurations on centrifugal pump performance. Locations of losses are detected using the entropy production rate, whereas the number of losses is evaluated using user-defined codes. Three volute collectors are selected based on their connections with standard pipes. A steady flow numerical analysis is performed to determine the performance parameters of the centrifugal pump and select a modified volute collector design. Comparing the results of experiments on the base and modified volute collectors confirmed that the proper design of the volute collector can help reduce the secondary flow losses at subsequent locations, which reduces the entropy production and losses. As compared to the base pump, the modified volute collector improved the pump efficiency by 3% at the duty flow.
