Unsteady aerodynamic forces estimation on a square cylinder by TR-PIV
Kurtuluş, Dilek Funda; Davıd, L. (Springer Science and Business Media LLC, 2007-02-01)
The unsteady aerodynamic forces acting on a square cross-sectional cylinder are investigated by means of time-resolved particle image velocimetry (TR-PIV) at Reynolds number 4,900. The objective of the investigation is to prove the feasibility of non-intrusive force measurements around two-dimensional bodies. The PIV measurements performed at a rate of 1 kHz enable a time resolved (TR) description of the vortex shedding phenomenon occurring at 10 Hz and to follow the time evolution of vortex dominated wake....

Unsteady MHD mixed convection flow in a lid-driven cavity with a heated wavy wall
OGLAKKAYA, F. S.; Bozkaya, Canan (Elsevier BV, 2018-11-01)
The unsteady mixed convection flow under the effect of an externally applied uniform magnetic field is investigated numerically in a lid-driven cavity with a sinusoidal wavy wall. The governing equations given in terms of stream function, vorticity and temperature are discretized by using the dual reciprocity boundary element method (DRBEM) in space and a two-level time integration scheme is employed in time discretization. The simulations focus on the effects of several physical parameters, namely Hartmann...

Unsteady flow analysis of two different arm stroke techniques in front crawl swimming using computational fluid dynamics
Bozkurt, Bilgehan; Güvenç Yazıcıoğlu, Almıla; Sert, Cüneyt; Department of Mechanical Engineering (2021-12)
This study analyzes how the propulsive force is created by the hand and arm in front crawl swimming. To answer this question, 12 swimming cases with variations in swimming velocity and arm velocity are compared using three dimensional straight and elbow angled arm models by doing unsteady flow analysis with computational fluid dynamics (CFD). The results show that the straight arm model creates more propulsive force than the angled arm. The results also reveal that linear hand velocity must be faster than s...
