6 FAQs about [Schematic diagram of wind wall vortex power generation]
What is a vortex generator?
1. Introduction A Vortex Generator (VG) is considered as a passive flow control device which modifies the boundary layer fluid motion bringing momentum from the outer region into the inner region.
How do vortex generators work in CFD?
Indeed, the Vortex Generators size is often similar to the boundary layer thickness and many small cells are needed in the VG geometry in order to have a reliable modelling of the flow. An alternative way of modelling VGs in CFD is to model the influence of the vortex generator on the boundary layer using body forces.
How effective is a vortex generator?
reversal (Kallweit 1986).Vortex generators are effective over an area several hundred time the vortex generator area. The effectiveness of the vortex generators depends on the ratio of vortex generator area o the primary surface area. Delta-type vortex generators are more us ful than rectangular forms. Win
How is vortex flow initiated?
Vortex flow was initiated solely through buoyancy arising from high surface solar radiation and maintained by sustained tangential inlet air flow through the vanes, with 39–41 °C ambient temperature, a maximum ambient horizontal wind speed of 8 m/s, and nominal vortex column diameter of 0.4 m registered from noon to 6:00 p.m.
What is the boundary layer thickness of a vortex generator?
The boundary layer thickness at the position of the vortex generator has been estimated from LDA measurements to be approximately δVG = 25 mm. The actuator, as seen in Figure 11, is a rectangular vane of the same height as the local boundary layer thickness, h = δVG, with a length of 2h.
How is a vortex created?
To create and maintain a vortex, a buoyancy force generated by a relatively large heat flux over a large surface area is required, such that warmed air is concentrated at the centre and rise. This flow induces an inward swirl and large angular momentum. These two contributions need to overcome surface friction and ambient shear flow.
