A 1:300 scale model of the tower and an inside fan for simulating the natural draft were provided by the company. The tests were performed in an air tunnel with a 5-foot octagonal test section. The model was mounted on a turn table, and a false floor was provided on the upstream side. All experiments were performed for the specified total-head loss across the grid section of about 22 velocity heads.eninfo:eu-repo/semantics/openAccessModellierung , Naturzugkühlturm624workingPaper
