Abstract:V diplomskem delu sem predstavil validacijo numeričnih orodij na primeru aerodinamike poenostavljenega vozila. Primerjal sem tri programe za računalniško dinamiko tekočin: Ansys CFX, Simscale in DualSPHysics. Na začetku na kratko predstavim osnovno problematiko aerodinamike vozil in zapišem nekaj osnovnih principov o numeričnih metodah. Nato opišem geometrijo, robne pogoje in nastavitve simulacij v vseh treh programih. Rezultate sem primerjal z eksperimentalnimi rezultati iz članka »Some Salient Features of the Time - Averaged Ground Vehicle Wake«. Analiziral sem natančnost rezultatov v odvisnosti od gostote računskih mrež. Glavni parameter po katerih sem ovrednotil rezultate je bil koeficient upora, poleg tega sem opazoval še hitrostna in tlačna polja.

Title:Validation of Numerical Tools for Bluff Body Aerodynamics
Abstract:The diploma thesis presents validation of numerical tools on the example of bluff body aerodynamics. I compared three programs for computational fluid dynamics: Ansys CFX, Simscale and DualSPHysics. At the beginning, I briefly present the basic problems of vehicle aerodynamics and discuss some basic principles about numerical methods. I then describe the geometry, boundary conditions, and simulation settings in all three programs. I compared the results with the experimental results from the article "Some Salient Features of the Time - Averaged Ground Vehicle Wake". I observed how the accuracy of the results changes with mesh refinement. The main parameter by which I evaluated the results was the drag coefficient. I also observed velocity and pressure fields.
Keywords:Validation, computational fluid dynamics, aerodynamics, Ahmed body, drag coefficient
