Interaction Detection in Aerodynamic Design Data
2009In large and complex aerodynamic systems the overall performance of a design is mainly defined by interactions between design areas rather than by single design regions. Therefore it is necessary to identify these interactions in order to be able to understand and improve the designs.

Pantograph aerodynamic effects on the pantograph–catenary interaction
Vehicle System Dynamics, 2006Some aspects about the influence on the current collection of the aerodynamic action on a pantograph, due to the incoming flow generated by train speed are investigated considering pantograph–catenary dynamic interaction. Starting from the quasi-steady theory formulation of the drag and lift forces on the collectors, and considering the turbulence of ...

Aerodynamics of Strake-Wing Interactions
Journal of Aircraft, 1979This paper reports on an experimental investigation where the longitudinal aerodynamic characteristics were determined up to high angles of attack for configurations employing parametric variations in strake span and wing sweep and includes correlations with theory. The investigation included both component and complete configuration studies to provide

Unsteady Aerodynamic Interactions in a Multistage Compressor
Journal of Turbomachinery, 1987The fundamental flow physics of multistage blade row interactions is experimentally investigated, with unique data obtained which quantify the unsteady harmonic aerodynamic interaction phenomena. In particular, a series of experiments is performed in a three-stage axial flow research compressor over a range of operating and geometric conditions at high

Interactions between underbody aerodynamics and aeroacoustics
2014Research has shown that lack of ground effect simulation in the wind tunnel could result in different flow conditions from those experienced by the vehicle on the road, influencing aerodynamic noise inside the cabin. The focus of this work is the influence of moving ground and rotating wheels on both aeroacoustic and aerodynamic measures for a typical ...

Hypersonic Magneto-Aerodynamic Interaction
2006The side-by-side numerical and experimental research for interdisciplinary phenomenon is a reflection of the stage of maturation for the modeling and simulation technology development. The detailed validation of hypersonic blunt body drag reduction technique using plasma injection was investigated by this approach. The major portion of the reduced drag

Aerodynamic and flight dynamic interaction in spin
Aircraft Engineering and Aerospace Technology, 2019PurposeThe purpose of this paper is to describe an integrated approach to spin analysis based on 6-DOF (degrees of freedom) fully nonlinear equations of motion and a three-dimensional multigrid Euler method used to specify a flow model. Another purpose of this study is to investigate military trainer performance during a developed phase of a ...

Turbulent aspects of plume aerodynamic interactions
31st Joint Propulsion Conference and Exhibit, 19955 . effects of plume/aerodynamic interactions; and, Detailed data on the structure of hot turbulent jets obtained at NASA LaRC has been analyzed using a two-equation (kc) modeling approach with extensions. The calculations have been found to be dependent on core turbulence characteristics and the turbulent Prandtl number.
