Numerical Simulation and Performance Forecast of Whole Flow Field in a Multi-Blade Centrifugal Fan |
|
| Abstract: | Aiming at the characteristics of a multi-blade centrifugal fan widely used in different environments,the full field model is built.The steady constant numerical simulation on the internal 3-D flow field is carried out under the design condition using the CFD method and the basic characteristics of internal flow field are presented.The reliability of the numerical method is verified through test and the several working conditions of multi-blade centrifugal fan are forecasted. |
| Keywords: | multi-blade centrifugal fan steady constant numerical simulation performance forecast |
