Abstract:V diplomski nalogi je obravnavana numerična analiza hidrodinamike kajaka Buran. Numerična analiza je izvedena na podlagi dveh numeričnih metod za simuliranje računalniške dinamike tekočin – metoda končnih volumnov (MKV) in metoda hidrodinamike zglajenih delcev (MHZD). Predmet zaključnega dela je določitev primernejše metodo za tovrstno aplikacijo, ter z izbrano analizirati vpliv geometrijske spremembe naklonskega kota nosu kajaka na hidrodinamično silo upora. Vrednosti vstopnih hitrosti za simulacije so pridobljene z eksperimentalno meritvijo. Uporaba MKV podaja hitre in zadostne rezultate, zato je bila uporabljena v simulacijah z novima geometrijama. Rezultati zmanjšanja naklonskega kota nosu kajaka za 3.9°, kažejo na zmanjšanje hidrodinamične sile upora za 3.5%.

Title:Numerical analysis of kayak hydrodynamics
Abstract:In the following diploma thesis, the numerical analysis of kayak Buran hydrodynamics is being discussed. Numerical analysis is performed on the basis of two different numerical approaches for computational fluid dynamics simulation: finite volume method (FVM) and smoothed particle hydrodynamics (SPH). The objective of diploma thesis is to determine the most appropriate method for such application and to analyze an impact of design change in kayak’s nose angle on total hydrodynamic drag force. Inlet velocity values for simulations are obtained by experimental measurement. According to its quick and fulfilling results, FVM was chosen for the simulation of new models. Geometrical decrease in kayak’s nose angle for 3.9° resulted in decrease of total hydrodynamic drag force for 3.5%.
Keywords:hydrodynamics, computational fluid dynamics (CFD), finite volume method (FVM), smoothed particle hydrodynamics (SPH)
