Abstract
Foam spreading experiments have been carried out in a 20 m diameter half-circular water pool and in a 5 m water channel without any thermal exposure. Maximum foam solution rate was 540 1/min. The foams used were an ordinary synthetic (Detergent) and an AFFF concentrate. The foam layer extension and the foam height were recorded, as functions of time. The foam height was at maximum 3 - 6 cm in the pool, and higher in the channel. At an application rate of 1.5 1/min/m² the pool was covered with foam in 50 s. The results from the experiments agree well with theoretical predictions as shown in a separate report.
