THEORETICAL CALCULATION OF AN EFFICIENT FAN WITH A SIDE INLET IN THE SHAPE OF AN AIR TRANSPORT SYSTEM

In this article, a new ovoid-shaped side inlet for a centrifugal fan in a cotton picker is proposed and its aerodynamic efficiency is theoretically substantiated. In order to maximize the efficiency of the fan, aspects related to the size and shape of the inlet surface were analyzed. A mathematical model of the ovoid shape was created and geometric parameters affecting the movement of the air flow were determined. The modeling results showed that the ovoid shape is effective in stabilizing the air flow entering the fan and reducing pressure losses.
