A novel labyrinth seal with staggered helical teeth (SHT) structure is proposed in this paper.
The influence of seal clearance, pressure drop, tooth number and eccentricity on the novel …

A flywheel energy storage system (FESS), with its high efficiency, long life, and transient
response characteristics, has a variety of applications, including for uninterrupted power …

The high-speed coolant pump is essential for electric vehicle thermal management,
ensuring optimal module temperatures. The pump impeller and bearing are combined into a …

As the most critical part of a hydropower station, reversible pump–turbines (RPTs) are facing
the trend of high parameterization (eg, high head and high rotation speed) with the rapid …

This work analyzes the operation conditions of the wavy-tilt-dam (WTD) mechanical seal
under different structural parameters using the DNS method. The pressure difference within …

Annular seals can induce fluid excitation forces that severely affect the stability of the pump
rotor systems. In this paper, a transient computational fluid dynamic method with a mesh …

In order to analyze the pump shaft stability of multistage centrifugal pump during the closed-
valve start-up process, the transient internal fluid field and structural field during the closed …

For a pressurized water reactor power plant, the reactor coolant pump (RCP) is a kernel
component. And for a canned motor RCP, the rotor system's properties determines its safety …

Flywheel energy storage system (FESS) with high efficiency, long life, transient response
characteristics can be widely used in uninterrupted power supply, renewable energy grid …
