Performance Analysis and Optimization of the Energy Indicators of an Axial Fan Through Some Constructive Changes Using Computer Simulations and Experimental Confirmation

This article aims to analyze the performance of an axial fan through experimental measurements, and to build a mathematical model for further analysis. The article presents a constructive change related to the position and geometric characteristics of the working blades, hub to tip ration, gap distance and through the simulations and experimental measurements performed, the performance of the fan taken in the study will be evaluated. For this purpose, a test bench that enables the construction of the characteristics of the axial fan was built. A mathematical model has been conceived, and the simulation program connects the constructive parameters with the performance characteristics of the fan. The CFTurbo program was also used for the realization of the 3d model of the fan. Using the technology of 3D printers, an improved prototype with constructive changes has been produced, which we will analyze in the experimental test.
