A shrouded wind turbine system has a number of potential advantages over the conventional wind turbine. A novel power-augmentation-guide-vane (PAGV) that surrounds a Sistan wind turbine was designed to improve the wind rotor performance by increasing the on-coming wind speed and guiding it to an optimum flow angle before it interacts with the rotor blades. The integration of the PAGV into the 3...

This research focuses on computational fluid dynamics modeling and experimental analysis of a shrouded wind turbine. A shroud turbine comprises with flanged encircling it for better energy utilization at low speed. The effects diffuser shape flange angle have been studied by performing flow field in Ansys Fluent condensing the size. CFD shows that cycloid gives 7% more velocity than straight sh...

We developed a new wind turbine system that consists of diffuser shroud with broad-ring brim at the exit periphery and inside it. The shrouded brimmed diffuser, which we called “wind lens turbine” (WLT), has demonstrated power augmentation by factor about 2–5 compared bare for given diameter speed. increase in output depends on shape length height. However, simple theory presented this paper ar...

Steam turbines employed in the sugar industry require high thermodynamic efficiency and absolute reliability. The AEG-KANIS Steam Turbine Company, situated in Nuremberg, West Germany, and for many years a supplier to the South African industry, developed such turbines based on 30 years of experience with turbines for all industrial purposes. A special feature of these typical turbines used for ...
