diplomsko delo
Abstract
V diplomskem delu je predstavljena primerjava tokovnih razmer pri obtekanju zraka okoli
dvodimenzionalnega profila NACA 4421 z zaprtim izstopnim robom (običajna oblika profila)
in novo obliko lopatice z odprtim izstopnim robom. Preračun je bil narejen s programskim
paketom ANSYS CFX 14. Rezultati podajajo primerjavo izračunanih vrednosti vzgonskih koeficientov,
ter diagrame tlačnih koeficientov in vektorjev hitrosti na profilu, za različne natočne
kote. Pravilnost načina izračuna je bila potrjena s primerjavo izračunanih vrednosti koeficientov
vzgona za primer zaprtega profila, z eksperimentalno pridobljenimi vrednostmi iz literature.
Rezultati simulacij kažejo, da je smiselno nadaljevanje raziskav izboljšanja tokovnih razmer
z uporabo lopatice z odprtim izstopnim robom.

Secondary title: |
Numerical analysis of flow over wind turbine airfoil |
Secondary abstract: |
The diploma work presents the comparison of flow conditions over two dimensional airfoil
NACA 4421 with closed trailing edge (normal airfoil shape) and new blade shape with open
trailing edge. The numerical analysis was made with ANSYS CFX 14 software package. The
results give the comparison of numerically obtained values of lift coefficient, as well as the
diagrams of pressure coefficients and velocity vectors on the airfoil, at different angles of attack.
Correctness of the method of computation was confirmed with the comparison of computed lift
coefficient values for closed trailing edge profile, with experimentally acquired values from
literature.
The results show, that it is reasonable to continue the research of flow conditions with the
use of open trailing edge airfoil. |
