Item Effect of wing surface contamination on aerodynamic characteristics(University of Žilina, 2023) Gego, Filip; Bugaj, MartinThe article is focused on determining the influence of wing surface contamination on aerodynamic characteristics. This work describes the description of the BL 215 airfoil on which the measurements were made, the factors affecting the change in aerodynamic characteristics, the method of obtaining the values necessary to draw a conclusion, and finally the comparison and evaluation of the resulting values. Through the geometric functions in the Inventor program, a wing model with a laminar airfoil BL 215 was created, the aerodynamic characteristics of which were calculated in the Ansys Fluent program.Item Simulations of aerodynamics(University of Zilina, 2021) Novák, Miroslav; Bugaj, MartinThe aim of the paper is to approach the issue of simulations in aerodynamics. To describe the physical rules and basic mathematical equations, which are essential in the use of computing techniques. The paper deals with CFD (Computational Fluid Dynamics) and informations which are necessary for its understanding, the author further describes different software programs used for simulation purposes. By means of analyzing technical papers, the author compares and describes software considering to their practical use. The author also describes the aerodynamic tunnels and clarifies the basic issues related to aerodynamic tunnels and discuss factors that affect the resulting measurement quality. The author deals with methods of measuring individual physical quantities that are the interest of simulation or measurement. At the end of the paper, the author compares the specific aerodynamic tunnels and the possibilities of measurements that aerodynamics tunnels provide.
