ISBN:
Category : Aeronautics
Languages : en

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.

Wind Tunnel Wall Correction
Author: B. F. R. Ewald
Publisher:
ISBN:
Category : Aerodynamics
Languages : en
Pages : 578
Book Description
This report was compiled by an international team of wind tunnel wall correction experts. It presents the present state of the art in wind tunnel wall corrections with a special emphasis given to the description of modern wall correction methods based on Computational Fluid Dynamics. This AGARDograph was planned by the AGARD Fluid Dynamics Panel to be a modern sequel of the successful AGARDograph 109 "Subsonic Wind Tunnel Wall Corrections", which was published in 1966. AGARDogaph 109 is still valid and continues to be used to provide wall corrections in many wind tunnels. Nevertheless, in the thirty two years since the publication of AGARDograph 109, much work has been done on the subject, and the influence of the new tool of numerical fluid dynamics was so strong, that a sequel to AGARDograph 109 was considered to be necessary.

Properties of Test Section Walls with Longitudinal Slots in Curved Flow for Subsonic and Supersonic Velocities (Theoretical Investigations)
Author: Bernhard H. Goethert
Publisher:
ISBN:
Category : Air flow
Languages : en
Pages : 23
Book Description
Mathematical expressions for the boundary conditions of longitudinally slotted walls are derived in order to facilitate calculations to determine the effectiveness of slotted walls in wind tunnels. A relationship is first established for the effect of flow curvature on the boundary conditions in the vicinity of conventional slotted walls for incompressible flow. This relationship is then extended to include the influences of protruding slats as well as of perforated cover plates at the base of the slots. Finally the extent to which the derived equations are valid for compressible flow in the subsonic and supersonic speed range is shown.

An Investigation of Several Slotted Wind Tunnel Wall Configurations with a High Disk Loading V/STOL Model
Author: Travis W. Binion
Publisher:
ISBN:
Category : Short take-off and landing aircraft
Languages : en
Pages : 72
Book Description
The investigation reported herein is the experimental portion of a unified theoretical and experimental search for a slotted wind tunnel wall configuration with minimal interference for conventional and V/STOL models. It is shown that theory and experiment are in excellent agreement for the classical case provided an appropriate expression is used to relate the wall geometry to the boundary condition. Classical data correction equations are not appropriate for the V/STOL case, however. An additional term, not predicted by theory, is needed to account for changes in the jet wake. Geometric parameters which influence the wall interference quantities are indicated. Wall configurations are shown which will produce interference-free force data to a jet-to-free-stream velocity ratio of 4.5. (Author).
