The multiphase rotodynamic pump, as an energy conversion device, is widely used in the
multiphase transport process. Visual measurement of unsteady flow in such a pump is of …

Flow and phase separation in gas–liquid multiphase pumps is easy to occur, which
deteriorates their performance and mixed transportability. Many research achievements …

有关叶片式气液混输泵全流道内流场特性的研究还不充分, 因此选取空气-水作为输运介质,
基于ANSYS_CFX 对一叶片式气液混输泵进行全流道数值模拟. 计算域采用ICEM_CFD …

This study explores the characteristics of twin-screw pumps when operated in turbine, ie,
reverse mode as an alternative to traditional control valves in piping systems for recovering …

Thus far, the break-up and the coalescence of bubbles have never been considered in the
simulations of the multiphase pumps, while the non-uniform bubble model (NUBM) …

Due to the effect of unit stages, the gas-liquid flow and the interphase forces in the
multistage multiphase pump are more disordered, which will affect the energy conversion …

The inlet bubble sizes and their coalescence and collapse behavior are the key factors
affecting the performance and transportability of the multiphase pump. In this paper, a …

The performance of multiphase pumps has a remarkable influence on the related industrial
application. In order to understand the flow field and gas-liquid phase interaction …

Vacuum pump is widely used in aviation, chemical, semiconductor and other fields because
of its superior performance. In order to study the internal flow characteristics and pump …

Pressure fluctuation in single-phase pumps has been studied widely, while less attention
has been paid to research on multiphase pumps that are commonly used in the petroleum …
