Book Description
The lift interference was calculated for a porous wall wind tunnel by a modified method of block cyclic reduction. This efficient, numerical method has indicated its accuracy by comparison with other available analytical and approximate solutions. A scheme is introduced to search for optimum wall configurations. The lift interference computed for an NACA 64-series finite airfoil in some optimum configurations has demonstrated the achievement of minimization of interference. The effect of test section length is also examined. (Author).

A Numerical Method of Calculating the Boundary-induced Interference in Slotted of Perforated Wind Tunnels of Rectangular Cross Section

A Numerical Method of Calculating the Boundary-induced Interference in Slotted of Perforated Wind Tunnels of Rectangular Cross Section PDF Author: James D. Keller
Publisher:
ISBN:
Category : Boundary layer
Languages : en
Pages : 26

Book Description
A numerical method is presented for calculating the boundary-induced interference at subsonic speeds in wind tunnels of rectangular cross section with slotted or perforated walls. The slot width or wall porosity can vary throughout the test section. The interference can be computed at any point in the test section. The model can be any configuration and can be located anywhere in the test section. Several examples are given, and comparison is made with other methods were available.

Wall Interference in Wind Tunnels with Slotted and Porous Boundaries at Subsonic Speeds

Wall Interference in Wind Tunnels with Slotted and Porous Boundaries at Subsonic Speeds PDF Author: Barrett Stone Baldwin

ISBN:
Category : Aeronautics
Languages : en
Pages : 46

Book Description
Linearized compressible-flow analysis is applied to the study of wind-tunnel-wall interference for subsonic flow in either two-dimensional or circular test sections having slotted or porous walls. Expressions are developed for evaluating blockage and lift interference.
