Abstract: Computational fluid dynamics were used to study the three-dimensional unsteady incompressible viscous flows in a centrifugal pump during rapid starting period (≈0.12 s). The rotational speed ...

Abstract: A one-dimensional (1D) system and three-dimensional (3D) component cosimulation method based on the method of characteristic (MOC) and computational fluid dynamics (CFD) was proposed to study the interaction between ...

Abstract: In applications where demand on a water supply system changes frequently and widely, the operating conditions of pumps always deviate from the design conditions, and this error leads to poor efficiency and reliability. For ...
