Analysis of Fluid Flow Characteristics Across the Darrieus Turbine in Irrigation Channels

This study simulated the characteristics of fluid flow that passes through Darrieus turbine before installation and testing were carried out. The purpose knowing can determine profile position maximum speed so design placement be improved. research method was out using dynamic computational simulations in three-dimensional form with steady state conditions, discretization second-order, convergent conditions when it reached 10-6. simulation results show above had lowest value because flowed relatively without disturbance which caused velocity to a almost same as incoming velocity. increased line 2 3 or across turbine. due turbulence generated by rotation While on 4 below lower than 3. did not have an impact speed. At four positions at Y=0.7 m hits increase expected turn also included distribution streamline several where contact channel wall low friction wall.
