Book Description
Axial Flow Fans: Design and Practice focuses on the design of axial flow fans and the practices involved in their applications. The manuscript first offers information on the fluid mechanics of ducted fans, boundary layer and skin friction relations, and aerofoil data for blade design. Discussions focus on flow deflection in cascade of aerofoils, pitching moment, lift, surface roughness in turbulent boundary layers, turbulent boundary layers in pressure gradients, laminar skin friction, viscosity and boundary layers, and similarity and non-dimensional numbers. The text then ponders on vortex flows in ducting and fan, ducts, and introduction to fan design methods. The book takes a look at the momentum and blade element considerations on free vortex flow of rotor and rotor losses. Topics include momentum considerations, profile drag, tip clearance losses, optimum conditions in terms of the flow and swirl coefficients, pressure relations and velocity vectors, and thrust and torque gradients. Tail fairing design and associated losses, overall efficiencies, torque, thrust, and power, and the design of fan unit with arbitrary vortex flow are also discussed. The publication is a dependable source of information for engineers and readers interested in the design of axial flow fans and practices involved in their operation.
