Design and Analysis of Nosecone of Kaplan Turbine at High Flow Conditions using Computational Fluid Dynamic Analysis

Abstract

In this generation multitechnology is developing day by day. Especially in producing electric power (current) using natural resources.  For every engineer, it’s very important to show enthusiastic to produce current from natural resources. Because of multitechnologies will develop by engineers only. The Kaplan turbine is an outward or inward flow reaction turbine. Here working fluid changes pressure as it moves through the turbine. Power is gained from both the Hydro static head and from the kinetic energy of flowing water. The Kaplan turbine is an outward flow reaction turbine, which means that the working fluid changes pressure as it moves through the turbine and gives up its energy.  Power is recovered from both the hydrostatic head and from the kinetic energy of the flowing water. In this project, Kaplan turbine with different nose cones were studied briefly and fluid flow analyzed for Kaplan turbine with different nose cones using Ansys CFD software.
