Download or read book Natural Tunnel Ventilation written by Robert L. Hayden and published by . This book was released on 1981 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ventilation system at the Eisenhower Memorial Tunnel was studied to determine the most energy efficient means of operation. The tunnel is a twin bore highway facility 8,940 feet long having a fully transverse ventilation system. Of the four mechanisms responsible for natural ventilation (piston effect, barometric pressure differentials, chimney effect, and outside wind effects) only the piston effect was found to be reliable. The TUNVEN computer model was found to be an excellent tunnel design and analysis tool. Through its application, a seasonal variation in airflow caused by icing in the flues was discovered.

Book excerpt: "TRB's National Cooperative Highway Research Program (NCHRP) Research Report 836: Guidelines for Emergency Ventilation Smoke Control in Roadway Tunnels presents guidelines for ventilation in roadway tunnels to facilitate human evacuation and emergency responder safety. These guidelines consider tunnel geometrics such as tunnel altitude; physical dimensions (i.e., length, cross section); type of traffic flow (i.e., single or bi-directional flow); and fan utilization and placement. They also consider cargo types and quantities as they pertain to fire heat release rates (FHRRs) and ventilation requirements. The guidelines determine the effects of ventilation on tunnel fires including fire size, and the interaction of firefighting and ventilation system operation. " -- Publisher description
