Rotating turbulent flows are widely existed in pumps, turbines, compressors and other fluid
machinery. The three-dimensional stochastic fluctuations are very strong in this kind of flow …

Although significant advances have been made in simulations of rotating stall and surge
with single passage or part-annulus passages models, quite little work has been devoted to …

The coaxial cylinder rheometer is widely used to measure the torque and rotational speed
(TN) of fresh concrete. TN can be transformed into the corresponding rheological …

Re-vamping of industrial turbo-machinery is commonplace in the oil and gas industry in
applications where subterranean combustion is used for oil extraction. The current case …

This paper deals with the construction of reduced order models (ROMs) for the simulation of
the interaction between a fluid and a rigid body with imposed rotation velocity. The approach …

为提高多级离心泵在多工况条件下水力性能的计算精度, 分别将计算域划分为四面体,
混合型和六面体网格, 采用RNG κ-ε 湍流模型进行数值计算, 与试验结果作对比 …

Turbines encounter blade failures due to fatigue and creep. It has been shown in the
literature that the primary cause of steam turbine blade failures worldwide can be ascribed to …

In order to improve the calculation accuracy of the hydraulic performance of multistage
centrifugal pump under multiple working conditions, the calculation domain was divided into …

This report covers the thesis work of the development of an oilmist-collector that makes it
possible for Husqvarna to perform long-term testing of chainsaws, while running with …

In order to verify the reliability of different turbulence models for predicting the aerodynamic
performance of transonic axial compressor cascade, using Fluent software and selecting SA …
