Vortex generators are used to overturn the momentum of flow in boundary layer, thereby preventing separation, and broadly aviation, wind power, heat exchange, different fields. It has been determined that capability an eddy current generator manipulate layer is proportional intensity vortex strength it excites. Although mathematical notion very well defined, there difficulties figuring out appl...

in this paper the effect of block shape vortex generators (vgs) on an air-water fin-tube heat exchanger has been studied experimentally using exergy analysis method. also the effect of these vgs on increasing heat transfer rate has been simulated numerically and the results show a good agreement with the experiments. in this research we used a wind tunnel to produce wind flow over heat exchange...

Vortex generators are devices that modify the wind behavior near surface of turbine blades. Their use allows boundary layer shedding transition zone to be varied. Bio-inspired design has been used improve efficiency aerodynamic and hydrodynamic systems by creating shapes present in animals plants. In this work, an experimental methodology is proposed study effect bio-inspired vortex their on st...

Vortex generators are used in aircraft wings and wind turbine blades. These devices allow them to maintain a stable turbulent behavior the wake. generators, or VGs, improve transition from laminar boundary layer regime, avoiding abrupt shedding. HAWT turbines have high rotational velocity. Currently, being redesigned with fixed vortex achieving higher energy production. This paper presents tunn...

Abstract To understand the micro-vortex structure of Microjet Vortex Generators, a plate with pitched and skewed jet holes was established. Simulations using SST-DDES method based on WENO scheme were conducted to analyse effect pressure, hole interval incoming boundary layer thickness flow structure. The pitch angle skew are 55 degrees 45 respectively. total pressure microjets ranges from 2.5 3...
