A Shock Tube Driven Transonic Wind Tunnel
A small transonic wind tunnel was designed, constructed and calibrated in order to provide a tool for the study and demonstration of transonic flow phenomena. The wind tunnel makes use of flow properties following the propagation of a shock wave along a tube in order to create the transonic flow. This is in contrast to conventional transonic facilities which are supplied from a reservoir or com...
متن کاملThe Use of Close Range Photogrammetry for Studying Ice Accretion on Aerofoil Sections
This paper describes the use of photogrammetry to measure and quantify ice accretion on an aerofoil section. A series of stereoscopic photographs was taken during the ice accretion on the section in an icing tunnel. From measurements made on these photographs with a Kern (Leica) DSR 14 analytical photogrammetric plotter, a series of three dimensional models of the ice surfaces was constructed. ...
متن کاملAerodynamics an aerofoil in transonic ground effect : numerical study at full - scale Reynolds num rs
The potential positive effects of ground proximity on the aerodynamic performance of a \Ving or aerofoil have long been established, but at transonic speeds the fonnation of shock waves betvveen the body and the ground plane would have significant consequences. A numerical study of the aerodynamics of an lu\E2822 aerofoil section in ground eiiect flight was conducted at freestream Mach numbers ...
متن کاملAnalysis of Viscous Transonic Flow over Airfoil Sections
A full Navier-Stokes solver has been used t o model transonic flow over three airfoil sections. The method uses a two-dimensional, implicit, conservative finite difference scheme for solving the compressible Navier-Stokes equations. Results are presented as prescribed for the Viscous Transonic Airfoil Workshop to held at the AIAA 25th Aerospace Sciences Meeting. "Jones" airfoils have been inves...
متن کاملFree boundary problems in shock reflection/diffraction and related transonic flow problems.
Shock waves are steep wavefronts that are fundamental in nature, especially in high-speed fluid flows. When a shock hits an obstacle, or a flying body meets a shock, shock reflection/diffraction phenomena occur. In this paper, we show how several long-standing shock reflection/diffraction problems can be formulated as free boundary problems, discuss some recent progress in developing mathematic...
