20.500.12556/DKUM-86470 Influence of Numerical Mesh Type on Airfoil Aerodynamic Characteristics In this paper, we will examine how different mesh types affect the aerodynamic characteristic of an airfoil. The airfoil used for this paper was the NREL S809. Three different mesh types were created, a blocked structured mesh, an unstructured mesh and a hybrid mesh containing a blocked structured mesh near the surface of the airfoil and an unstructured mesh on the outside perimeter. Steady state simulations were performed for angles of attack between 0°and 22°. Lift and drag coefficient for all created meshes were compared to experimental results from literature. From angles of attack between 2° and 8° all three meshes predict similar lift and drag coefficients. We encountered problems with convergence for the unstructured mesh at angles of attack higher than 8°. Structured and hybrid mesh had similar lift and drag coefficients across all angles of attack. computational fluid dynamics NREL S809 structured mesh unstructured mesh hybrid mesh energetika aerodinamika dinamika tekočin strukturna mreža nestrukturna mreža hibridna mreža true false false Univerza v Mariboru, Univerzitetna založba Angleški jezik Slovenski jezik Znanstveno delo 2023-12-04 14:34:15 2023-12-04 14:42:48 2023-12-05 03:13:46 0000-00-00 00:00:00 2019 0 0 Str. 251-255 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2019-02-27 620.9:532.5 96247297 1024341852 7th_International_Symposium_on_Applied_Electromagnetics_2019.pdf 7th_International_Symposium_on_Applied_Electromagnetics_2019.pdf 1 437BEC023C52110C47DCA818F5EFF289 7d2b0b7d9a2533b365b38040040ff7f08f509dc644888d1f5ea74b7626218b9c ea7bc00d-92aa-11ee-9395-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=174568 https://doi.org/10.18690/978-961-286-241-1.34 0 f6bfd023-92aa-11ee-9395-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=174569 Fakulteta za energetiko Univerzitetna založba Univerze v Mariboru Conference proceedings 0 0 0
