Wind funnel power generation principle

How do modern wind energy systems work?

Modern wind energy systems are of giant structures having a turbine generator on the top of tower at a height of 80 metres with control mechanisms like yaw control and pitch control. With this modern wind energy systems, exploitation of wind energy at low wind speeds is not possible, operation and maintenance and yaw control are difficult.

Is funnel based wind energy harvesting system feasible?

In this paper, design and experimental setup of funnel based wind energy harvesting system (FBWEHS) is explained in detail. For studying the feasibility of this new approach, a subsonic wind tunnel testing is carried out. Further smoke test in the wind tunnel is also carried out for visualizing the flow of air into the nested funnel.

How much does wind power grow at the exit of a funnel?

T ⎜ ⎟ . (4) ⎝ d ⎠ From the diagram of variation (figure 2) of the power of wind at the exit of the funnel, according to the funnel diameter ratio (D / d), the wind power grows by 3 times if the diameter of the entry of the funnel is 20% larger than the diameter of the exit.

How do wind turbine generators work?

In this system, the wind is captured at the top of the funnel-shaped system, then it will be concentrated to runs through a Venturi for increasing velocity. turbine generators are located at the optimum area of wind speed for converting wind power to electrical energy.
