Abstract
U ovom radu su provedene numeričke simulacije s ciljem određivanja koeficijenta otpora trenja ravnih ploča. Dan je pregled literature, ukratko je objašnjena računalna dinamika fluida te je prikazan matematički model viskoznog strujanja fluida, koji se temelji na Reynoldsovim osrednjenim Navier–Stokesovim (eng. Reynolds-Averaged Navier-Stokes, RANS) jednadžbama. Dan je prikaz k-ω SST modela turbulencije, koji je kombinacija k-ω i k-ε modela turbulencije te je prikazan postupak verifikacije i validacije rezultata dobivenih numeričkim simulacijama. Numeričke simulacije su provedene za ekvivalentnu i ne ekvivalentnu ravnu ploču te njihove modele. Uz pomoć komercijalnog programskog paketa STAR-CCM+ definirani su proračunska domena i rubni uvjeti te je generirana mreža konačnih volumena. Dobiveni koeficijenti otpora trenja su uspoređeni s korelacijskom linijom model-brod ITTC-1957 i Schoenherrovom linijom trenja te je pokazano da su rezultati numeričkih simulacija viskoznog strujanja oko ravnih ploča zadovoljavajuće točnosti.
Abstract (english)
In this study numerical simulations are performed in order to assess frictional resistance coefficient of flat plates. Literature review is given along with a brief description of Computational Fluid Dynamics. Furthermore, a mathematical model of viscous fluid flow based on Reynolds Averaged Navier-Stokes (RANS) equations is given as well. k-ω SST turbulence model, which is a combination of k-ω and k-ε turbulence model, is presented. Verification and validation procedure of the obtained results is shown as well. Numerical simulations are carried out for equivalent and non-equivalent flat plates and equivalent and non-equivalent flat plate models. Computational domain and boundary conditions are defined, and mesh is generated utilizing commercial software package STAR-CCM+. The obtained frictional resistance coefficients are compared with model-ship correlation line ITTC-1957 and Schoenherr friction line. It has been shown that numerical simulations of viscous flow around flat plates can provide satisfactory results.
