Abstract

A turbine duct 1 comprises expansions 2, 3 and air deflector 5 having depressions 4 on the outer side of duct and expansions which control turbulence flow around the turbine. The air deflector has a plurality of depressions 6 which can be placed within its vertical stabilisers 23 for controlling fluid flow around turbine duct 1 which combined increase fluid flow velocity in side ducted turbine.

Description

Ducted turbines air deflector and housing
Background art
This application describe inventions which future improve inventions described in previous applications GBI 309889.2 and GBI 209923.0.
This devices are used for increasing the velocity of fluid flow in side ducted turbine by means of pressure controls around turbine by air deflectors and turbulence control.
Statement of invention
To further improve fluid velocity inside ducted turbines some additional features are introduced. Those are depressions within frontal side of air deflector and as well as the outside of main duct (shroud) and its expansions, both intake expansion and exit expansion. The role of the depressions within main duct and its expansions are to reduce the negative effects of turbulent area of fluid which passing by after pass over frontal expansion. The role of the depressions on air deflector is to additionally slow down fluid when fluid hits deflector. On this way pressure area around ducted turbine is additionally increased which directly affect fluid flow velocity increase and positive turbine performance.
Introduction to drawings
Figure 1 presents axonometric front view of ducted turbine with depressions on its duct and duct's expansions as well as with depressions on air deflector.
Figure 2 presents axonometric back view of ducted turbine with depressions on its duct and duct's expansions as well as with depressions on air deflector as well as depressions (dents) on turbulence control ring, inner side of duct and its expansions and depressions (dents) on back (inner) side of air deflector.
Figure 3 presents enlarged detail "A" from figure 2.
Detail description
To further improve fluid velocity inside ducted turbines some additional features are introduced within this application. Those are depressions 6 within frontal side of air deflector 5 and as well as the outside of main duct (shroud) 1 and its expansions both intake expansion 2 and exit expansion 3. In this case air deflector is shaped as two rings, one horizontal one vertical, bonded, with radii bond between them. Depressions 6 are in this case placed within vertical stabilizers 23. If beside deflector 5 there additional deflectors above or below deflector 5 on each of those deflectors could be placed depressions also. The role of the depressions 4 within main duct 1 and its expansions 2, 3 are to reduce the negative effects of turbulent area of fluid which passing by after pass over frontal expansion 2. The role of the depressions 6 on air deflector 5 is to additionally slow down fluid when fluid hits deflector 5. On this way pressure area around ducted turbine 10 is additionally increased which directly affect fluid flow velocity increase and positive turbine performance. Of course sometime turbine 10 do not need to have air deflector 5. If deflector 5 exist, depressions do not have to exist both on duct 1 and expansions 2, 3 and air deflector S but either on duct 1 and/or expansions 2, 3 or only air deflector 5. For maximal turbine 10 performance, these new features could be combined, on variety of ways, with already described, in previous patent applications, turbulence control features like: turbulence control ring 9, depressions 19,20 on turbulence control ring 9, depressions 18 on nacelle 25, intake 15 and nozzle 16 of nacelles 24, 25, depressions 26 on inner side of duct 1 and duct expansions 2, 3, depressions 21 of inner side of air deflector 5.
