Programme

Wednesday, April 6^th, 2022

The whole day is dedicated to excursion to various facilities and laboratories of the Czech PC ERCOFTAC members. Some of the facilities are in Prague, some are in other places around. All excursions will be organized in groups, depending on the interest of participants. It is suggested to choose one excursion from the list below:

1. Aerodynamic laboratory in Nový Knín – offered by the Institute of Thermomechanics, CAS

2. Centre of Vehicles for Sustainable Mobility in Roztoky u Prahy – offered by the Department of Automotive Engineering, FME CTU

3. Turbulence laboratory in Prague – offered by the Institute of Thermomechanics, CAS

4. Fluid mechanics laboratory in Prague – offered by the Department of Fluid Mechanics and Thermodynamics, FME CTU

For all excursions the participants meet on April 6^th at 9:00 in front of the main building of the Faculty of Mechanical Engineering. From this place individual groups of participants will travel to their destinations. Only participants who registered for the excursion can be admitted.
