| Aiming at the disadvantages of high test cost and low efficiency in the design optimization process of cooling fans, a simulation method for fan performance test based on CFD was proposed. The cooling fan performance simulation test was based on CATIA modeling software and FLUENT fluid simulation software. Through CFD calculation, the analysis and research of the cooling fan aerodynamic performance parameters were realized. The simulated turbulence model used the RNG κ ε model, the rotation model used the MRF multiple reference coordinate system model, and the solution method used the SIMPLE algorithm. By comparing the simulation data with the test data, it was concluded that the simulation error of each performance parameter was less than 9%, and the simulation accuracy was within an acceptable range. The results show that the condition setting and calculation method of the cooling fan performance test simulation can meet the general engineering application, the simulation model has certain application value, and it can be used to study the aerodynamic performance of the cooling fan. |
