Sažetak
This paper is a summary of the ongoing numerical investigation analyzing the influence of modelling parameters on numerical simulation of 2-D unsteady transonic flows. The focus of research lies on a simulation of self-sustained shock oscillation (buffet phenomena), since this mechanism can play an important role in the aeroelastic behaviour of modern slender wing aircrafts. Three different 2-D profiles have been used in the investigation and the following modelling parameters have been varied: (a) turbulence modelling, (b) flow solver spatial discretization schemes, and (c) temporal resolution parameters.
