Simulations of aerodynamics

The 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.
