Energy Science &Engineering, Volume 14, Issue 2, Page 764-779, February 2026.Based on entropy theory, this study presents a comparative numerical analysis of the flow energy dissipation (FED) in a VTSP under two distinct operating conditions: pump condition and turbine condition, both characterized by relatively high hydraulic efficiencies of 88.9% and 87.4%, respectively. In pump condition, the highest FED production occurs in

Study on Negative Pressure Approach for Surface Profile Measurement With Coolant Condition
The Journal of Engineering, Volume 2026, Issue 1, January/December 2026.In this work, we proposed a negative pressure approach, which could help a 2D laser sensor conduct in‐process measurement with coolant condition. The applicator to conduct a negative pressure approach was studied and designed. The experimental results show that the negative pressure approach could help 2D laser beam conduct measurement on a workpiece ...

Gaoya dianqi, 2017 对于高压断路器灭弧室动态流场的数值计算,往往采用动网格技术进行模拟,目前众多涉及动网格的流场模拟计算都采用Ansys Fluent来完成的。相比之下,Ansys CFX具有较广泛的应用范围和诸多优点,能够解决前者的诸多不足,但其缺点是不能直接解决涉及较大变形的动网格计算。文中针对此不足,基于UX和Ansys CFX两款商业软件,通过对它们进行二次开发,得到了一种适用于动态流场计算程序;通过对某高压断路器灭弧室实际流场进行动态计算,验证了该方法的可行性和准确性。该方法在一定程度上解决了Ansys ...
