Numerical Investigation of Flow Profile and Performance Test of Cross-Flow Turbine

Nang Saing Nuet, Myat Myat Soe, Audrey Thu

Open full text 1 citations

Abstract

The paper refers to the numerical analysis of the two stages of inlet and outlet blades of cross-flow turbine.A Computational Fluid Dynamics (CFD) steady state flow simulation has been performed using ANSYS CFX 17.Numerical method has also been used to calculate and predict the efficiency of the turbine.Velocity distribution and within the flow domain has been also characterized.The simulation includes flow domain and blades.The turbine has a specific speed of 44 (metric units), an outside runner diameter of 150 mm.Simulations has been carried out using k-ε turbulence model.The objectives of this study were to analyze the velocity of the Crossflow within the runner and to characterize its performance for different runner speeds.The CFD simulations results were compared with experimental data and were consistent with turbine efficiency.
