Longitudinal Ventilation Systems


Investigations on the Optimization of Longitudinal Ventilation Systems for Road Tunnels based on the Development of a Model Tunnel

Logos of project participants  

The overall aim of the research project is the optimization of longitudinal ventilation systems for road tunnels in regular operation and in a incident. Investigations of the flow-mechanical conditions in a model tunnel to be developed open up questions e.g. for the diffusion of smoke on a reduced scale. In addition, the applicability and meaningfulness of numerical simulation models are first checked and afterwards the models developed - based on the findings obtained at the model tunnel.
