Cilj ovog završnog rada bio je analizirati promjenu tlaka i polja brzina restriktora koristeći komercijalni softver ili softver otvorenog koda. Krenuvši od 3D CAD modela restriktora računali smo parametre protoka zraka ovisne o samim dimenzijama restriktora te o postavljenim graničnim uvjetima. Daljnjom analizom i manipulacijom geometrije CAD modela dobili smo negativ koji nam je bio baza za numeričku analizu u ANSYS softveru. Končano, obavljenom analizom dobili smo grafičke prikaze promjene tlakova i polja brzina iz kojih se može uvidjeti ponašanje zraka koji struji kroz sami restrikor. This final project's goal was to use either commercial or open-source software to analyse the restrictor's pressure change and velocity field. We determined the airflow characteristics based on the restrictor's dimensions and predetermined boundary conditions starting with a 3D CAD model of the restrictor. We created a mesh that served as the foundation for the numerical analysis in the ANSYS programme by doing additional analysis and geometric modification on the CAD model. Finally, we were able to see how the airflow behaved as it passed through the restrictor thanks to the graphical representations of pressure changes and velocity fields that the analysis had produced.
