Abstract
Ovaj rad se primarno fokusira na usporedbu proračuna strujanja fluida, primjenom računalne dinamike fluida, oko dvije realne geometrije krila. Jedna geometrija je konačno ravno krilo, a druga je isto krilo s dodatkom uređaja za kontrolu intenziteta vršnog vrtloga. Na početku rada objašnjeni su osnovni problemi pojave vrtloga kod zrakoplova. Nakon toga je opisan osnovni algoritam rješavanja spregnutog sustava jednadžbi brzine i tlaka u nestlačivom strujanju. Poslije toga je na jednostavnome primjeru dvodimenzijskog strujanja evolucije Taylor-Green vrtloga prikazan način mjerenja numeričke greške uz pomoć poznavanja analitičkog rješenja Navier-Stokesovih jednadžbi. Veličine numeričkih grešaka prikazane su za različite parametre diskretizacije. Na kraju ovog rada prikazani su rezultati proračuna za dvije geometrije, koji uključuju usporedbu intenziteta simuliranih vrtloga u nizvodnome toku.
Abstract (english)
This work is primarily focused on the comparison of the calculation of fluid flow, using computational fluid dynamics, between two real wing geometries. The first geometry is a final straight wing, while the other is the same wing with wingtip devices used for the control of the wingtip intensity. At the beginning of this work, the basic problems of the appearance of the wingtip vortices at the aircraft are introduced and explained. Afterwards, the basic algorithm for solving the system of equations of pressure velocity coupling for incompressible flow is described. Subsequently, a simple example of measuring the numerical errors in comparison with the analytical solution of the Navier-Stokes equations of the two-dimensional Taylor-Green vortex has been shown. The size of numerical errors is presented for various parameters of discretization. At the end of this work the results of the calculation for two geometries are presented, with comparison of the intensity of simulated vortices in downstream flow.
