Abstract
Numerical algorithms for the flow of cooling tower axial fans in the flow wise direction and span-wise direction have been transformed and solved by the Matlab application with a graphical user interface to obtain the optimum axial fan design. The analyses of the velocity and pressure distributions were achieved using the thin airfoil theory. The fan has a single rotor with no inlet or outlet guide vanes and produces a large amount of flow rate and a small pressure rise. Then, the air flow governing equations for the new design were solved using the commercial computational fluid dynamics (CFD) code ANSYS CFX-16.0. A comparison between the new design and an existed design (usually a mean line design approach) of the ammonia cooling tower fan in El-Delta for Fertilizers Company in Talkha City, Egypt was done. The efficiency of the new design is higher than that of the existed one. The new designed fan is capable to deliver more air flow or the same flow rate at higher pressures with the same power requirement. This enables the installation of new high resistance fill, which increases the area of contact between air and water to increase cooling efficiency.
