Abstract
U ovom radu se ispituje utjecaj promjene uzdužnog nagiba i dubine urona kobilice na hidrodinami čki otpor uronjenog dijela jedrilice klase Optimist. Istisnina je izračunata za ukupnu masu jedrilice i jedriličara od 80 kg. U proračunu je uzeta brzina jedrilice od 1,5 m/s. Za sve slučajeve proračunska domena je diskretizirana korištenjem računalnih programa Salome i cfMesh. Numeri čki proračun za stacionarne uvjete strujanja uz zanemaren utjecaj valova je izvršen u programskom paketu OpenFOAM. U radu je su prikazani i analizirani rezultati te su prikazana polja brzine i tlaka za najzanimljivije slučaje.
Abstract (english)
Goal of this work is to determinate the influence of pitch angle and keel depth on drag force of sail-boat class Optimist hull. Drag force is analyzed for the sail-boat cruise velocity of 1.5 m/s. Computational domain is discretizated using Salome and cfMesh program package, and various cases of pitch angle and keel depth where studied. Numerical analysis for stationary flow conditions is executed in OpenFOAM program package. The results are presented trough velocity and pressure fields of most interesting cases, so as in form of force-pitch angle diagrams.
