A fan that blows air from a ring without any exterior blades is known as an air multiplier, sometimes
known as a bladeless fan. Its hidden vanes steer the gathered airflow through a toroid, blowing a thin,
smooth airflow at high velocity across the surface of the tube or toroid from a continuous slot.
Electrical fans have been used for decades. Blades of the fan rotates and makes the air flow and
creates thermal comfort. Air multiplier fan is a fan which blows air from a ring with no external
blades. Consistent and steady breeze. Just like normal fans, it sucks the air and supply it to) users but
do not cool the air. Attach a convergent nozzle for getting the required cooling effect. The
effectiveness of active geometric parameters is taken into account while analyzing the aerodynamic
performance of a bladeless fan. By modelling a bladeless fan inside a 2m 2m 4m room, airflow via
this fan was examined. By resolving conservations of mass and momentum equations for the
aerodynamic research, the analysis of the flow field inside the fan and the evaluation of its
performance were achieved. An Eppler473 airfoil profile was utilized to create the bladeless fan's
cross section.
