Thermal Warm Fog Dissipation - Heat Requirements and Projected Utilization of a System for Travis AFB, California.
Abstract
Climatological records of fog occurrence and wind characteristics in fog are used to design a passive ground-based heat system for the dispersal of warm fog at Travis AFB, California. The array of heat sources is patterned after that described by FIDO engineers for parallel winds. The burner array shape is similar to an elongated horseshoe that encloses the upwind end of the runway, with the parallel legs 450 ft apart terminating 240 ft short of a 700-ft-long cross leg. An analysis of air traffic records in combination with fog statistics indicates that the system could be used to aid approximately 900 (2600) landings and takeoffs in an average (extreme) year during the fog-plagued months from November to February. Assuming a burn time of five minutes per landing or takeoff, the heaters could be expected to operate approximately 75 (260) h and consume approximately eleven (48) million gallons of fuel in an average (extreme) year. During the time the system is operating it generates heat at a rate of approximately 10 billion BTU/h. (Author)
