Ventilation System Design for a Roadway Tunnel in Acapulco, México

There are several industrial methods for tunnel ventilation system design. In particular, for tunnels where axial flow fans are applicable, there are specialized computer programs that calculate the various pressure drops that consider wall friction and local losses due to signs and appurtenances, and considering vehicle emission factors based on up-hill or down-hill conditions, determine the n...

Bi-directional Coupling of Simulation Tools with a Walkthrough-System

Visualising is a method used to help experiencing a nd understanding causal cohesions in simulation processes. For this purpose, tools for visualising are already implemented in prevalent simulation systems. The user creates his simulation model and generates a 3-dimensional (2,5-dimensional) visualising by means of the simulation system. This helps examining the process which makes it easier f...
