Kurzbeschreibung (Abstract)
According to the guidelines VDI- 2280: 2005 and VDI 3781: 2017 Part 4 an exit velocity of at least 7 m/s vertically upwards should be aimed for a better distribution of the corrosive exhaust air such as from laboratories. This speed ensures sufficient dilution and undisturbed removal of the exhaust gases with the free air flow. The corrosion-resistant mechanical regulator, developed for this purpose, is an automatic regulator for flow speeds that are constantly above a specified minimum speed using minimal aerodynamic forces (pressure and friction) and the spring force. Initially, analytical calculation and CFD analysis with OpenFoam are examined. The graphic evaluation shows velocity fields at different volume flow, the pressure fields and streamlines.
