Numerical Analysis of Crosss Flow Hydokinetic Turbine by Using Computational Fluid Dynamics

摘要: The invention of cross flow turbine industry from straight blades the Darrieus was modified by Alexander Gorlov into helical shape. There have been several research projects dealing with design and analysis for tidal applications. This paper deals Numerical a hydrokinetic (CFHT) blades. Static optimum blade velocity constant pressure conditions performed fixed pitch using Computational Fluid Dynamics (CFD) in Fluent 15. Solidworks used to carry out 3D modeling turbine. hydrofoil shape NACA 0018 created airfoil coordinate database. Two different turbulence models Spalart-Allmaras (One-Equation model) sst-k (Two ndash;Equation were employed compute compare results. Pressure profiles, drag lift coefficients are calculated under steady 1.5 m/s.
