Twisted Contact Structures in Turbulent Flows

The “hairpin” vortical structure initiated from a conceptual model of Theodorsen refers to a Ω-shaped vortex with two streamwise-oriented legs connected via a raised spanwise-oriented arch. Both computational and experim...

Determining the sensitivity of Data Envelopment Analysis method used in airport benchmarking

In the last decade there were some important changes in the airport industry, caused by the liberalization of the air transportation market. Until recently airports were considered infrastructure elements, and they were...

[b]ALOAD - a code to determine the concentrated forces equivalent with a distributed pressure field for a FEM analysis[/b]

The main objective of this paper is to describe a code for calculating an equivalent system of concentrate loads for a FEM analysis. The tables from the Aerodynamic Department contain pressure field for a whole bearing s...

Unsteady effects in flows past stationary airfoils with Gurney flaps due to unsteady flow separations at low Reynolds numbers

This paper presents the analysis of the unsteady flows past stationary airfoils equipped with Gurney flaps at low Reynolds numbers, aiming to study the unsteady behavior of the aerodynamic coefficients due to the flow se...
