An approximate method for the eecient calculation of stagnation streamline quantities in hypersonic ows about spheres or cylinders is suggested. Based on the local similarity of the ow eld the two-dimensional Navier-Stokes equations are simpliied to a one-dimensional approximation for the stagnation streamline. The dimensionally reduced equations are solved(More)
Received Abstract. An approximate method for the eecient calculation of stagnation-streamline quantities in hyper-sonic ows about spheres or cylinders is suggested. Based on the local similarity of the ow eld the two-dimensional Navier-Stokes equations are simpliied to a one-dimensional approximation for the stagnation streamline. These equations are solved(More)
The Ernst-Mach-Institute (EMI) of the Fraunhofer-Society is dealing with a wide spectrum of subjects in the fields of applied physics, mechanical and civil engineering. The EMI department for numerical simulation supports the institute and external customers with high-performance software applications in the fields of compressible flows, structural(More)
The most-widely used approach to explosion consequence analysis is the classical engineering method based on the combination of TNT equivalence, scaled distances and overpressure-based damage levels. This approach rests on established and easily comprehensible elements and permits a fast assessment of explosion consequences. There are however several(More)
Multi-Dimensional fluidand structural dynamics problems are solved by computational methods based on Arbitrary Lagrange Euler (ALE) formulation of the continuum mechanical conservation equations. The paper presents a new modification of the radial basis function (RBF) based mesh motion scheme, which combines the RBF interpolation with the breadth-first(More)
