A TRACER INVESTIGATION OF THE WAKE DOWNWIND OF AN ALUMINIUM SMELTER HALL
Abstract
Nine SF6 tracer experiments were conducted at the ÅSV Høyanger Aluminium Smelter during April, 1978. Tracer emitted at heights ranging from 1 m to 11 m above the roof of the smelter hall become entrained within the wake and subsequently reentered the hall through the fresh air supply vents. Approximately 1% of the SF6 released above the roof during southerly winds infiltrated the hall, while as much as 11% of the SF6 released above the roof during northerly winds infiltrated the hall.
