Abstract The object of this paper is the Saint-Venant torsion a solid elliptical cylinder made orthotropic homogeneous piezoelectric material. We find shape cross section which does not warp under applied torque. sizes section, has maximum value torsional rigidity for given cross-sectional area, are also determined.

We investigate the prediction of turbulent flow around a canonical square cylinder at Re= 22000 solving unsteady Reynolds-averaged Navier-Stokes (URANS) equations. The limitations URANS modelling are overcome through application data assimilation technique involving feedback control term, allowing to drive predictions towards reference data. Using regularly-spaced temporally-resolved that extra...

The wake of a yawed square cylinder undergoing steady flow was examined by employing particle image velocimetry (PIV) technique. present study is concerned with the independence principle (IP) for examining effect yaw angle (α) on velocity signals and vortical structures. normalized Strouhal number indicates that IP no longer applicable when α reaches 45°. At = 45°, distorted vorticity contour ...
