Download or read book Off-Design Computer Code for Calculating the Aerodynamic Performance of Axial-Flow Fans and Compressors written by National Aeronautics and Space Adm Nasa and published by . This book was released on 2018-11-07 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: An off-design axial-flow compressor code is presented and is available from COSMIC for predicting the aerodynamic performance maps of fans and compressors. Steady axisymmetric flow is assumed and the aerodynamic solution reduces to solving the two-dimensional flow field in the meridional plane. A streamline curvature method is used for calculating this flow-field outside the blade rows. This code allows for bleed flows and the first five stators can be reset for each rotational speed, capabilities which are necessary for large multistage compressors. The accuracy of the off-design performance predictions depend upon the validity of the flow loss and deviation correlation models. These empirical correlations for the flow loss and deviation are used to model the real flow effects and the off-design code will compute through small reverse flow regions. The input to this off-design code is fully described and a user's example case for a two-stage fan is included with complete input and output data sets. Also, a comparison of the off-design code predictions with experimental data is included which generally shows good agreement. Schmidt, James F. Unspecified Center...

Book excerpt: 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.

This book was released on 1951 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation has been conducted to determine the effects of the wall boundary layer upon the performance of an axial-flow fan rotor. Tests were conducted at low Mach numbers and at one blade angle on a fan designed to have uniform downstream tangential velocity. The maximum disturbed-flow region of the six boundary-layer configurations tested exceeded one-half of the annular width of the duct and the peak efficiency was reduced 2 1/2 percent for this condition. The over-all loss in efficiency may possibly be reduced by decreasing the blade pitch angle in the boundary-layer region to conform to the upstream velocity profile.
