The invention of bladeless fans has revolutionized the design technology in the fan industry in recent years. Bladeless fans are unique in shape and highly efficient in performance. This study aims to find an optimized geometry for a bladeless ceiling fan comparable to a conventional fan. Through Design of Experiments analysis, the study determined that a fan diameter of 1.4 m, jet width of 2.55 mm, jet orientation of 91.21o, and jet velocity of 3 m/s are the optimized parameters for a bladeless fan. CFD simulations showed an average velocity of 1.32 m/s and a velocity spread of 76%. Compared to conventional ceiling fans, the bladeless fan recorded a 60% enhancement in air delivery values. The study concludes that the future solution for economical ceiling fans lies in the application of bladeless technologies.
- The design technology in the world of fans has been revolutionized by the invention of bladeless fans in recent years. Bladeless fans are unique in shape and highly efficient in performance. At present, a bladeless ceiling fan on the concept of bladeless Air-Multiplier is not available. The present study intends to find an optimized ge-ometry for the bladeless ceiling fan which is comparable to a conventional fan. Design of Experiments analysis was followed in the present study and found that a fan diameter of 1.4 m, jet width of 2.55 mm, jet orientation of 91.21o, and jet velocity of 3 m/s are the optimized parameter for a bladeless fan within the applied constraints. An average velocity of 1.32 m/s and a velocity spread of 76% were calculated during CFD simulations. The results were compared with the experimental data of conventional ceiling fans and a 60% enhancement in air delivery values were recorded for the bladeless fan. It is concluded that the answer to the future economical ceiling fan lies in the application of bladeless technologies.
