Large Eddy Simulations of three-dimensional turbulent compressible flows in curved duct of rectangular cross-section are presented. Strong secondary flows and turbulent structures are the typical features of this type of flow: these are responsible for mos ...

For buildings which are stabilized by core or shear walls, the vertical members are generally subjected to compressive normal forces N and certain imposed angles of rotation θ. Similar in this respect are non slender bridge piers. These rotations originate ...
Partial flow rate operation of hydroturbines with constant pitch blades causes complex unstable cavitating flow in the diffuser cone. A particle image velocimetry (PIV) system allows investigating the flow velocity field in the case of a developing cavitat ...
We present practical and theoretical, stage-by-stage analysis of light propagation around a 90degrees corner in a two-dimensional photonic crystal waveguide. Using a series of different samples we quantify the coupling efficiency between the conventional r ...
This paper considers a helicopter-like setup called the Toycopter. Its particularities reside first in the fact that the toycopter motion is constrained to remain on a sphere and second in the use of a variable rotational speed of the propellers to vary th ...
This paper presents a method to model and optimize brushless dc motor for a solar airplane. In order to obtain the optimal solution for the given specifications, all free parameters are analyzed globally in one go. For this, the commercial optimization sof ...
Developing a research autonomous plane for flying in a laboratory space is a challenge that forces one to understand the specific aerodynamic, power and construction constraints. In order to obtain a very slow flight while maintaining a high maneuverabilit ...
