Near-Wall Flow Characteristics of a Centrifugal Impeller with Low Specific Speed

Near-Wall Flow Characteristics of a Centrifugal Impeller with Low Specific Speed

In order to study the near-wall region flow characteristics in a low-specific-speed centrifugal impeller, based on ANSYS-CFX 15.0 software, Reynolds averaged Navier-Stokes (RANS) methods and renormalization group (RNG) k-ɛ turbulence model were used to simulate the whole flow field of a low specific...
