On the determination of the aerodynamic coefficients of highway tunnels

Journal of Wind Engineering and Industrial Aerodynamics, 2002
Abstract The determination of the aerodynamic coefficients of highway tunnels is crucial to set up an accurate theoretical model of tunnel ventilation. Their appropriate values vary with situations, such as traffic conditions, auxiliary facilities in tunnel, jet fan performance, and so on, and accordingly shall be determined in real situations.

Further Developments in Consistent Unsteady Supersonic Aerodynamic Coefficients

Journal of Aircraft, 1971
A finite element method to evaluate unsteady supersonic aerodynamic coefficients consistent with structural stiffness and inertia properties of a lifting surface is described. The grid and element system on the wing surface can be the same as in the structural analysis.

Use of the aerodynamic equivalence method in the determination and analysis of the aerodynamic coefficients of asymmetric bodies

Fluid Dynamics, 1986
In [1] the validity of the linear method of aerodynamic equivalence (AE) was demonstrated and the results of calculating the aerodynamic characteristics (ADC) of certain asymmetric (nonaxisymmetric) bodies, differing only slightly from the axisymmetric, were presented. In this paper a nonlinear AE method is proposed.

On the Evaluation of Aerodynamic Influence Coefficients

1988
In this paper numerical schemes are discussed to reduce the computational work involved with the evaluation of the aerodynamic influence coefficients of panel methods. The applicability of these schemes is investigated to the calculation of potential flow around an airfoil.

Surrogates for the Aerodynamic Coefficients of Supersonic Airfoils

53rd AIAA Aerospace Sciences Meeting, 2015
Generally, physical phenomena are represented in the form of explicit mathematical expressions that stem from basic governing equations. However, in many cases, having these expressions may not be achieved and a considerable part of our knowledge relies on abstract numbers produced via lab experiments or computer simulations. In the absence of explicit

Aerodynamic Coefficients and Risk‐consistent Design

Journal of Structural Engineering, 1983
A simple procedure is presented for estimating the reliability of windsensitive structures whose orientation is not specified. The procedure is based on a second moment reliability approach and makes use of: (1) Aerodynamic coefficients obtained experimentally as functions of wind direction, and (2) climatological data consisting of sets of largest ...

Aerodynamic Influence Coefficients from Strip Theory

Journal of the Aerospace Sciences, 1959
T N ANY AEROELASTIC ANALYSIS by collocation methods, both structural and aerodynamic influence coefficients must be known. We consider here the derivation of the aerodynamic influence coefficients (AICs) from the simplest of the aerodynamic theories—that of strip theory in which the flow along any section of the wing can be considered as two ...

Effect of Cold Jet Plume on Aerodynamics Coefficients

Journal of Spacecraft and Rockets, 2015
Experiments are carried out on a blunt-cone-cylinder-flare geometry to study the effect of Mach 2.65 jet plume interaction with Mach 5 freestream on overall aerodynamic coefficients. Supersonic jet plume pressure ratios Pj/Pinf of 0 to 158 are simulated, and the angle of attack α is varied from +4 to −4  deg.
