Tunnel Type Wind Mile Design

Abstract

This study designs a tunnel type wind mill to increase the capability of wind energy capture. The main design works including the wind collection duct which can rotate along with the wind direction. This makes the wind enter the duct in best condition. After the wind enter the duct, both the direction of the duct is changed to vertical direction which makes the wind direction changes to downward. In the meantime, the diameter of the duct is also changed. The change of the diameter of the duct increases the speed of wind flow. A wind turbine with a nose is used to collect the wind energy. The nose makes the speed of the air flow increase more. In addition to the increasing the speed, the other advantage is to make the air flow flows to the outer part of the turbine blades. It is well known that the outer part of the turbine blade can get more energy than the inner part of the blade. This design can more wind energy than regular wind turbine.
