Abstract: It was made to improve a fan efficiency by varying the bare length defined as the distance between the tongue tip and the impeller tip, and the divergent angle at the outlet of the scroll casing. It is concluded that (1) The larger the bare length is, the higher the flow rate is. (2) When the bare length is 15mm, the fan efficiency is highest. (3) The fan efficiency is highest at the divergent angle θ=0°. (4) The smaller the bare length is, the larger the total pressure drop is due to the skin friction.
