Abstract: The Stokes flow in a cylindrical quadrant duct with a rotating wall was analytically and numerically studied. Based on mathematics and fluid dynamics theory, the analytical expressions of three velocity components were ...

Abstract: Many methods have been proposed to identify servo system parameters. However, problems still remain in widely applied offline identification methods, for example, the describing-function-based relay feedback method has the ...

Abstract: The journal bearing is pivotal for the advancement of refrigerant compressors. While the gas–oil lubrication mechanism has been explored in some previous studies, the dynamic coefficients of gas–oil-lubricated bearings in ...

Abstract: Combined damage caused by cavitation and abrasion is a serious problem concerning hydraulic structures and machinery operating in hyper-concentrated sediment-laden rivers. Conceptualization of a model for simulation and ...
