Abstract
Završni rad prikazuje stacionarnu analizu strujanja fluida Darrieusove vjetroturbine s vertikalnom osi H-tipa, koja se sastoji od tri, međusobno jednako razmaknute lopatice, upotrebom Ansys programa za provedbu računalnih simulacija. Promatrani problem je dvodimenzionalan budući da se promatra jedan presjek vjetroturbine po visini lopatica, odnosno okomito na os vrtnje. Analiza strujanja temelji se na izračunu koeficijenata uzgona pojedinih lopatica unutar kuta zakreta od početne pozicije od 0° do 180°, za svakih 10° rotacije. Kroz rad se prolazi kroz proces izrade geometrije, preko izrade numeričke mreže, do numeričke analize i prikaza rezultata, sve unutar pojedinih komponenti sustava Ansys Workbench aplikacije. Dobiveni rezultati vezani za vrijednosti koeficijenata uzgona na pojedinim lopaticama turbine pokazuju određene pravilnosti, međutim, nije do kraja potvrđena njihova valjanost. Konture statičkih i dinamičkih tlakova te konture brzine, za pojedine položaje, dobro opisuju strujanje fluida unutar pretpostavki stacionarnog strujanja.
Abstract (english)
This paper covers steady state numerical analysis of fluid flow on Darrieus H-type vertical axis wind turbine, with three equally spaced turbine blades, using Ansys simulation software. Observed problem is two-dimensional, where the geometry is derived from a cross-section perpendicular to the turbine axis of rotation. Fluid flow analysis consists of calculation of lift coefficients of each individual turbine blade for angle of attack in range 0°-180°, with 10° resolution data extraction. This work covers modeling geometry, through mesh creation, simulation setup and result processing, all by using system components of Ansys Workbench application. Produced results of lift coefficients, for each of the blade, show some regularity in structure but haven’t been validated. Results of contour of static and dynamic pressure and velocity magnitude contours give a good description of fluid flow within assumptions of steady state flow.
