Inlet Shroud Angle of a Shrouded Wind Turbine
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 4
Abstract
In order to utilize the wind power more economically, it was suggested that a specially designed shroud could be used to enclose the wind turbine so that its performance could be increased. Various geometries are discussed; it is shown that with a shroud a significant power augmentation can be achieved. For improving the performance of shroud, a ring-shaped flap or boundary layer control technique is introduced. It is shown that up to 80% improvement in the shroud power augmentation can be obtained by the use of an appropriate ring-shaped flap while proper bleeding of the shroud's external flow into its inner rear part will increase its power augmentation by about 25%. The main aim of this project is to reduce the length of the shroud so that such shrouds can be economically implemented for larger wind turbines and thus the power output can be increased efficiently. If we can reduce the length (L/D ratio) of the shroud it will reduce the total volume of material required, the strength of the support, space needed. If the shroud can be incorporated with the large wind farms the total power generation and efficiency will be increased.
