Perturbation Analysis of Unsteady Transonic Flow through Cascadesr, in this regime even small amplitude oscillations of the blades may cause large variations of the magnitude of the aerodynamic forces and moments. Therefore, an inexpensive method for the prediction of steady and unsteady pressure distributions on oscillating blades in cascades would be particular

Viscous Transonic Flow in the Vicinity of a Corner Pointe of a sonic line is assumed. A local potential Vaglio-Laurin flow type and a flow with a free stream line are considered as limiting ones. It was shown that the character of the flow in incident laminar boundary layers depends on the pressure gradient that is established from the solution of a glob

Summary and Evaluation of the Workshop “Numerical Simulation of Compressible Viscous-Flow Aerodynamih the experimentally observed data, to date only pressure measurements. The discussion of the comparisons and of the difficulties associated with the numerical simulations leads to suggestions for further experimental and theoretical work.

Viscous-Inviscid Strategy and Computation of Transonic Buffet from a time-consistent viscous-inviscid coupling, converged at each time-step. Results are shown both for a supercritical and an NACA0012 airfoil. The computed buffet-onset, and buffet time-evolutions, are compared with available experiments versus incidence and Mach number.

Transonic Computations by Multidomain Techniques with Potential and Euler Solversearized ADI non-iterative scheme. A coupling of a potential and of an Euler solver permits the three-dimensional calculation of a supersonic jet in a transonic outer flow with fitting of the jet surface.

On the Development and Application of Software based on the Framework of Cartesian Coordinatesow at low speeds, and to analyse axisymmetric flows as well as flow over wings and wing-body combinations. Several results are presented here for each of the above flow situations which clearly demonstrate the efficacy of the Cartesian grids for dealing with complex geometry shapes while simulating transonic flow in a full-potential formulation.

Asymptotic Methods in Transonic Flow Theoryin the boundary layer, i.e. the internal region where the dissipative factors are of prime importance. Their role becomes decisive in the understanding and explaining of two fundamental phenomena: separation and stability, both showing specific features when the external velocity is close to the speed of sound.
