The attraction water for the fish lift enters partly at the upstream end of the tank, partly through side or floor diffusers and gratings.
Thus, the purpose of this study is to examine the effect of geometrical design of a floor swirl diffuser on the aspects of airflow rate, number of diffuser blades, angle of attack of diffuser blades, and the grille thickness.
Floor swirl diffuser is one of the commonly used diffusers in underfloor air distribution (UFAD) system.
Geometrical design of the floor swirl diffuser will affect the airflow pattern of the indoor environment.
Bloodhound's huge marquee was packed out with festival-goers talking to the team about the Bloodhound show car, its EJ200 jet engine, the massive aluminium diffuser floor (which had literally come straight from the factory), and the huge range of other bits we had on display.
It also moves the exhaust exits further into the centre of the car, abandoning attempts to gain an aerodynamic benefit from blowing them at the area where the rear wheels meet the floor in an attempt to 'seal' the diffuser and increase downforce.
Underfloor air distribution (UFAD) systems use the underfloor plenum beneath a raised floor to provide conditioned air through floor-mounted diffusers, which typically discharge cool air with both horizontal and vertical momentum components.
The team principal, Stefano Domenicali, has admitted that Ferrari got distracted in focusing too much attention on their F-duct system, but they ran an improved version in Turkey and since then the upgrades have come on stream at a steady rate; the exhaust-blown diffuser appearing in Valencia and a new floor at the last race in Singapore.
Air from the bargeboard area flows under the floor beneath the driver before feeding straight into the diffuser.
The rules governing that area were changed ahead of this season to ban so-called exhaust-blown diffusers, which blew exhausts gases along the floor of the cars to 'seal' the gap between the floor and the rear wheels and enhance aerodynamic downforce.
