ENGINE FAN DIAMETER DEFINITION

Turbofan - Wikipedia
The engine was aimed at ultra quiet STOL aircraft operating from city centre airports. In a bid for increased efficiency with speed, a development of the turbofan and turboprop known as a propfan engine was created that had an unducted fan. The fan blades are situated outside of the duct, so that it appears like a turboprop with wide scimitarPrinciples · Common types · Turbofan configurations · Overall performance · Early turbofans
Mechanical Flex Fans | JEGS
Engine mounted fans are less effective in traffic because they pull little air when the engine RPM is low. If engine to radiator clearance is a problem, some electric fans can be used as a pusher fan and placed on the grille side of the radiator. Pusher fans usually free up engine compartment space.Derale 19118 · JEGS 52194
When to increase diameter of fan for a turbofan?
The main reason to increase is the fan diameter is because it is more efficient to move large volume of air at lower speed compared to a smaller volume at higher speed, at the end of the day m.V gives you the thrust you need. Hope this is helpful.

HOW TO SELECT A FAN OR BLOWER - Cincinnati Fan
A centrifugal blower wheel draws air into the inlet of the blower housing, through the wheel, and discharges it at 90° out through the discharge of the blower housing. An axial fan uses a propeller to draw the air into the fan and discharges the air in the same axial direction.
