Smith, J. (author)The displacement effect of a body in an air stream increases when regions of non-linear flow, such as locally supersonic flow, occur. Therefore, a subsonic formulation of the displacement effect must fail for transonic flow conditions. It is shown that, for the particular case of a two-dimensional aerofoil, a subsonic formulation may...report 1986

Smith, J. (author)The applicability of a multi-velocity-component static pipe, proposed by CALSPAN ATC, for measuring boundary velocity vector distributions in behalf of wall interference assessment, has been explored in two-dimensional flow. Comparisons with alternative methods to derive the local flow angle from measured pipe pressures as well as analyses of...report 1985

Smith, C.J.E. (author), Hewins, M.A.H. (author)Rotating bending fatigue tests have established that glass bead and alumina grit blasting have only a slight effect on the fatigue properties of 2014-T6 aluminium alloy. Exposure to salt fog for 8 hours or alternate immersion in 3½% salt solution for 3 days reduces the fatigue strength from 170 MPa to 107 MPa and 64 MPa respectively but...report 1984

Maarsingh, R.A. (author), Labrujère, T.E. (author), Smith, J. (author)The present paper describes two alternative correction methods for wall interference based on measured boundary conditions. In both methods it is assipied that at or near the tunnel boundary the flow velocity will be measured in magnitude and direction and that the main part of the flow field may be considered irrotational and subsonic. One...report 1984

Smith, J. (author)The applicability of two-dimensional flexible solid wall test sections for three-dimensional testing is theoretically investigated for linearized subsonic flow. The method uses known interference velocity distributions along a targer line (derived from a method of images for this particular study). From these, wall shapes are calculated that...report 1984

Woodrooffe, J.H.F. (author), Morisset, L.E. (author), Smith, C.A.M. (author)A simplified mathematical solution to predict transient off tracking of multiple vehicle combinations is presented. The generalized equations assume a constant radius curve of any angular duration with a tangent lead in and run out. The validated solution yields the off tracking of a vehicle or vehicle combination with respect to a track mounted...report 1983

Smith, J. (author)Modern developments in wind tunnel wall correction methods are for a major part directed towards the use of in situ measured boundary conditions in order to eliminate the need to describe the complicated aerodynamic characteristics of test section walls. This paper presents a short general review of the principles of such methods for 2D flow....report 1982

Smith, J. (author)A "measured-boundary-condition" method for determining 2D wall interference has been developed. It applies measured "wall" pressure distributions and a model representation to determine the 2D interference flow field associated with the presence of the test section walls. Special attention has been paid to the model representation. The...report 1981

Smith, E.C. (author), Zwets, J. (author)Methods of closing tidal channels as at present applied in Bangladesh have been developed since many years in an imperical way. As the size of closure gaps in future will increase, a more systematic approach will be required to close those bigger gaps. It was therefore agreed that as a first step bottom protection mattresses should be introduced...report 1978
