G100S axial flow fan simulation comparison analysis

This paper conducts a comparative simulation for different structural layout schemes of the new G100S axial flow fan, with the motor layout position and its supporting guide vane as the main modification direction, while the fan length and guide tongue angle are appropriately adjusted according to the motor position. CFD analysis and calculation are used to compare and study the performance of the axial-flow fan. The results show that the axial flow fan with rear motor, air outlet cone integration, and large angle guide tongue layout has greater wind speed, longer injection distance, more uniform distribution of outlet flow field traces, greater wind pressure at the air outlet, and faster flow stability convergence. This work will provide technical support for designing orthogonal experiments in the direction of fan miniaturization and lightweight.
