Sun, Z. (author)The micro vortex generator (MVG) is used extensively in low speed aerodynamic problems and is now extended into the supersonic flow regime to solve undesired flow features that are associated with shock wave boundary layer interactions (SWBLI) such as flow separation and associated unsteadiness of the interaction system. Numerous experimental...doctoral thesis 2014

Sun, Z. (author), Schrijer, F.F.J. (author), Scarano, F. (author), Van Oudheusden, B.W. (author)The three-dimensional instantaneous flow organization in the near wake of a micro-ramp interacting with a Mach 2.0 supersonic turbulent boundary layer is studied using tomographic particle image velocimetry. The mean flow reveals a wake with approximately circular cross section dominated by a pair of counter-rotating streamwise vortices...journal article 2012

La Torre, F. (author)A new satellite philosophy, developed during the last two decades, suggests to make satellites smaller and lighter rather than bigger and heavier. In other words, large (?m3), single system satellites are being replaced by ?eets of small (?dm3), so-called micro-satellites. Future developmentsmay result in swarms ofmicro satellites ?ying through...doctoral thesis 2011

Souverein, L.J. (author)Shock wave boundary layer interactions (SWBLI) are a common phenomenon in transonic and supersonic flows. The presence of shock waves, induced by specific geometrical configurations, causes a rapid increase of the pressure, which can lead to flow separation. Examples of such interactions are found in amongst others rocket engine nozzles and on...doctoral thesis 2010

Theunissen, R. (author)As an experimental tool, Particle Image Velocimetry has quickly superseded traditional point-wise measurements. The inherent image processing has become standardized though the performances are strongly dependent on user experience. Moreover, the arduously selected image interrogation parameters are applied uniformly throughout the image...doctoral thesis 2010

Mathijssen, T. (author)Ever since the 1950s delta wings are being used as an efficient planform for supersonic flight. Over time extensive research on the aerodynamics of this type of wings has been performed using many different measurement techniques. Due to technical difficulties, measurements on delta wings in a supersonic flow are still scarce and often limited...master thesis 2008

Abbate, G. (author), Kleijn, C.R. (author), Thijsse, B.J. (author), Engeln, R. (author), Van de Sanden, M.C.M. (author), Schram, D.C. (author)The gas dynamics of a stationary hot-gas jet supersonically expanding into a low pressure environment is studied through numerical simulations. A hybrid coupled continuum-molecular approach is used to model the flow field. Due to the low pressure and high thermodynamic gradients, continuum mechanics results are doubtful, while, because of its...journal article 2008

Humble, R.A. (author), Scarano, F. (author), Van Oudheusden, B.W. (author)The unsteady flow features of a series of two-dimensional, planar base flows are examined, within a range of low-supersonic Mach numbers in order to gain a better understanding of the effects of compressibility on the organized global dynamics. Particle image velocimetry is used as the primary diagnostic tool in order to characterize the...journal article 2007

Arnal, D. (author)The global objective of the SUPERTRAC project is to explore the possibilities to delay laminar-turbulent transition on supersonic aircraft wings. The following techniques are investigated: micron-sized roughness elements, anti-contamination devices, suction and shape optimization. This paper provides an overview of the project and describes in...conference paper 2006

Daumas, L. (author), Dinh, Q.V. (author), Kleinveld, S. (author), Rogé, G. (author)Preliminary results on shape optimization of a wing-body configuration aiming at reducing sonic boom overpressure will be discussed. The optimization process uses a CAD modeler and an Euler CFD code with adjoint. Thickness, scale, twist and camber at section level were used to obtain gains in ground pressure signature.conference paper 2006

Alauzet, F. (author)This paper presents an accurate approach to simulate the sonic boom of a supersonic aircraft. The near field flow is modeled by the conservative Euler equations and is solved using a finite volume approach on adapted unstructured tetrahedral meshes. Then, from the CFD solution, the pressure distribution under the aircraft is extracted and used...conference paper 2006

(author)The three-dimensional, transient, non-isothermal flow of melt, slag and oxygen/argon is simulated for a 335 t combined blowing converter with six-hole top lance and 14 bottom tuyeres. The calculation is based on the Reynolds averaged Navier-Stokes (RANS) equations and the Standard k-epsilon model. The time-dependent formation of the melt...conference paper 2006
