Abstract

The study presents the design and optimization process for high-performance ceiling fans aimed at energy savings and environmental protection. Utilizing Computational Fluid Dynamics (CFD) numerical simulations with the k-ω SST turbulence model and the multi-reference frame (MRF) method, various fan blade configurations were evaluated to enhance airflow and improve energy consumption efficiency. The design process focused on selecting the aerodynamic profile (airfoil), optimizing the twist angle, and distributing the chord length. Among the tested options, the optimized version yielded superior results in airflow distribution, torque, and noise characteristics. The grid convergence analysis with 11.5 million elements validated the accuracy of the simulations. The addition of winglets helped reduce tip vortex phenomena and sound intensity, lowering it by up to 20 dB. A frequency spectrum analysis model using the Fast Fourier Transform (FFT) was applied to assess the sound characteristics in detail and identify noise-causing frequency components. The final design meets technical requirements and manufacturability, achieving optimal performance at a speed range of 220–225 rpm for the 5-blade configuration and 265 rpm for the 3-blade configuration. Energy performance parameters were measured according to Vietnam national standards (TCVN) for electric fans, validating the simulation results and ensuring suitability under real operating conditions.
