Designing a Bulb turbine’s wing profile in hydropower plants and manufacturing a small model

Abstract

Turbine Buld is a low water column turbine; the entire mass of machine is placed in the river bed which has a small capacity of less than 10MW. However, turbine designers and manufacturers always keep a secret about the turbine’s wing profile and operating characteristics. The manufacturers only provide basic dimensions for installation of the machine. Therefore, in order to have continuous operation with highly effectiveness of a hydroelectric and to reduce the dependence on experts from the manufacturers as well, the design of the turbine’s wing profile is very important in both engineering and economy. From the design drawings, manufacturing process is built for maintaining, reparing, and operating the hydroelectric plant. In this paper, basic steps for designing a Bulb turbine’s wing profile are presented. From the steps, a small model of turbine’s wing profile is designed and manufactured.
