Abstract:
The conventional ceiling fan employs fan blades to facilitate air distribution in the surrounding area, thereby inducing a cooling effect within the room. However, this airflow generates unpleasant noise resulting from the interaction between the blades and the air. Furthermore, conventional fans pose potential hazards to individuals in close proximity. In contrast, bladeless fans serve as an excellent alternative in addressing these issues, as they lack visible blades. Moreover, they exhibit lower power consumption, leading to reduced electricity costs. These fans have recently emerged for domestic applications, prompting research aimed at designing a bladeless fan with optimal performance. Computational Fluid Dynamics (CFD) techniques are utilized to analyze and evaluate the designed fan, followed by the fabrication of a prototype model. Literature reviews pertaining to this subject confirm the advantageous aspects of bladeless fans compared to conventional counterparts. However, it is worth noting that certain design improvements can be implemented to enhance the fan's ability to provide sufficient airflow to a larger number of individuals while increasing its overall performance.
