Yuvaraj, R. (author)This thesis work illustrates the first of its kind solution to this problem of lack of seeding at vortex core in air flows, by the use of Helium Filled Soap Bubble (HFSB) which is a neutrally buoyant tracer particle in air flows. To analyse the lack of seeding in the vortex core, a 2D numerical simulation of particle motion in vortex flow is...master thesis 2016

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

Hagmeijer, R. (author)Computational grids are used for the discretisation of partial differential equations (PDE's) such that solution of the resulting system of algebraic equations for the discrete values of the dependent variables provides an approximation to the solution of the system of PDE's. When the discretisation of the partial differential equations (PDE's)...report 1997

Hoeijmakers, H.W.M. (author)An analysis is presented of results of a computational method to simulate the steady compressible vortical type of flow around a 65deg sharpedged cropped delta wing. The discussion emphasizes some more fundamental aspects of the numerical simulation such as the separation of the flow, the structure of the leadingedge vortex core and the flow...report 1991

Hoeijmakers, H.W.M. (author)The physical aspects, the mathematical modeling, the development and application of computational methods for the simulation of vertical flows are described. The highReynolds number vortex flows considered are assumed to be steady, subcritical and such that the structure of the flow is wellordered and consists of thin shear layers and slender...report 1989

Elsenaar, A. (author)As part of the joint International Vortex Flow Experiment, force and pressure measurements have been carried out on a 65 deg delta wing configuration in the transonic and supersonic wind tunnels of NLR. Out of these data three test cases were selected by the organizing committee of the GAMM WORKSHOP on the "Numerical Simulation of Compressible...report 1986

Hoeijmakers, H.W.M. (author)In part I of this report a method is described for computing the incompressible flow about slender, thin wings with leadingedge vortex separation. It is assumed that both the wing and the flow field are symmetric with respect to the x—z plane. The method can handle delta—like wings of quite general planform and shape. However, in the...report 1986

de Bruin, A.C. (author)The three dimensional flow field around delta wings with leadingedge vortex flow can be computed with panel methods. However, secondary flow separation may occur on the leeward surface of the wing. The associated free vortex sheet can be modeled in the potential flow calculation method, if the location of the secondary separation is provided by...report 1983
