Vyšetření odporu a vztlaku při obtékání těles různého tvaru

Abstract

The bachelor thesis deals with investigation of drag and lift coefficient during the flow over different bodies. The first part is devoted to an introduction to the theory of flow and flow over bodies. The second part concentrates on laboratory measurements of aerodynamic instrument from company HELAGO and measurement with propeller anemometer. Measurement of drag and lift was made for objects of different shapes and for different velocity of air flow. In the last part of the work the calculations of drag coefficient from the measured values was done for each object and the results were compared with tabular values.
