摘要

Taking a certain type of small high-speed centrifugal fan as the research object, improved design of volute tongue with lateral step and biological surface bionic method. Constructed a three-dimensional model, used Ansys Fluent software, and use the LES model for transient numerical simulation calculations, evaluated the reliability of the improved volute tongue. Noise simulation and experiment we...
