摘要

水泵作为水轮机,将水力能转化为电能,是供水管网管理的新趋势。迄今为止,这种装置的应用很少,因为缺乏对技评项目和技评与水系统之间相互作用的充分研究。总体效率,在流量和压力变化下的灵活性,对非稳态条件的响应仍然是悬而未决的问题。本文用数值计算方法对其中的一些问题进行了讨论。

Numerical simulation on pump as turbine: Mesh reliability and performance concerns
A pump used as turbine (PAT) for the transformation of hydraulic energy in electricity is the new trend in the management of water distribution networks. So far few application of such devices are known for the lack of adequate studies on the PAT project and on the interactions between PAT and the water system. Overall efficiency, flexibility under flow rate and pressure variations, response to unsteady state conditions are still open questions. Some of these problems are discussed in the paper by numerical computation.
