We, the authors, Editors and Publisher of the journal IETE Journal of Research, have retracted the following article:

Qifei Li, Qi Huang, Feng Zhou & Zhenggui Li (2021) Numerical Simulation of Stress Process of Runner Blade in Pump Turbine Transition Process, IETE Journal of Research, DOI: 10.1080/03772063.2021.1967794

Since publication, the authors have identified issues with the experimental data and analysis.

As this directly impacts the validity of the reported results and conclusions, the authors alerted the matter to the Editor and Publisher and all have agreed to retract the article to ensure the integrity of the scholarly record.

We have been informed in our decision-making by our policy on publishing ethics and integrity and the COPE guidelines on retractions.

The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as ‘Retracted’.

我们， IETE Journal of Research期刊的作者、编辑和出版商，撤回了以下文章：

李启飞, 黄启, 周峰 & 李正贵 (2021) 泵涡轮过渡过程中转轮叶片应力过程的数值模拟, IETE Journal of Research, DOI: 10.1080/03772063.2021.1967794

自出版以来，作者已经确定了实验数据和分析的问题。

由于这直接影响报告结果和结论的有效性，作者已将此事告知编辑和出版商，并且所有人都同意撤回文章以确保学术记录的完整性。

我们在决策过程中了解了我们的出版道德和诚信政策以及 COPE 关于撤稿的指南。

撤回的文章将保持在线以维护学术记录，但将在每页上以数字水印标记为“已撤回”。
