U ovom diplomskom radu izvršena je numerička simulacija turbulentnog strujanja oko krila aviona pomoću programskog paketa ANSYS Fluent 2020R2. Cilj ovog rada je dati uvid u primjenu napadnog ruba te njegov utjecaj na aeroprofil. Objašnjen je matematički model viskoznog strujanja fluida, koji se temelji na Reynoldsovim osrednjenim Navier-Stokesovim jednadžbama (RANS). Za potrebe numeričke simulacije izrađena su tri modela aeroprofila. Prikazana je raspodjela polja brzina i polja tlakova, kao i aerodinamički koeficijenti uzgona i otpora. In this thesis a numerical simulation of turbulent flow was performed around the airfoil using ANSYS Fluent 2020R2 software package. The main goal of this thesis is to give insights into the application of tubercles on the airfoil. Description of mathematical model of viscous fluid flow is given, which is based on Reynolds Averaged Navier-Stokes (RANS) equations. Three models of airfoil were created for the purpose of numerical simulation. Distribution of velocity and pressure fields are shown, as well as the aerodynamic lift and drag coefficient. |
