Air flow measurement through compact heat exchanger in wind tunnel
Žůrek, Michael ; Vondruš, Jan (referee) ; Šebela, Kamil (advisor)
This thesis describes Formula Student competition, overview of used aerodynamic devices, placement of compact heat exchangers on these monoposts and current monopost Dragon e2. Next section examines commonly used compact exchangers and their aerodynamic drag, mainly caused by angling and ununiform flow. Subsequently is described the process of preparation, measurement in wind tunnel and measuring devices. An algorithm was created and described, which was used for evaluation of measurement, influence of some factor was commented. On the right-side compact exchanger, methods of measuring were compared, namely pneumatic probe, pressure difference and turbine anemometer. On left side exchanger were observed influence of various aerodynamic elements. Lastly alternative position behind vehicle rear axle was measured.
