20.500.12556/DKUM-69036 Primerjalna analiza dveh CFD programov na aerodinamičnem profilu vetrne turbine Comparison analysis of two CFD programs on wind turbine blade aerofoil Namen zaključnega dela je primerjava rezultatov simulacij dveh CFD programov na aerodinamičnem profilu vetrne turbine. Izvedene so bile numerične simulacije v programih Ansys CFX 17.1 in Ansys Fluent 17.1. Pri različnih napadnih kotih smo simulirali obtekanje aerodinamičnega profila NACA 0015 in rezultate primerjali z meritvami, pridobljenimi iz literature. Primerjali smo koeficient vzgona, koeficient upora, potek tlaka po profilu pri različnih napadnih kotih in točke odcepitve na aerodinamičnem profilu. V obeh CFD programih smo naredili stacionarne simulacije z k-ε in SST modelom turbulentnega toka. The purpose of this final thesis is comparing analysis of two CFD programs on a aerodynamic wind turbine airfoil. We carried out numerical simulations in Ansys CFX 17.1 and Ansys Fluent 17.1. We simulated the aerodynamic airfoil NACA 0015 at various angles of attack. We compared the results of numerical simulations with results we got from literature. We also compared the lift coefficient, drag coefficient and the pressure distribution across the airfoil at various angles of attack and separation point on aerodynamic airfoil. We have made stationary simulations k-ε and SST turbulent fluid models in each CFD program.
