Web25 de mai. de 2024 · A closed configuration with both high pressure and low pressure chambers is shown in the figure, but there are other configurations of blowdown tunnels. Some blowdown tunnels, called indraft tunnels, do not use a high pressure chamber, but open the plenum chamber to the atmosphere. WebFor most Open Circuit tunnels, fan assemblies are located downstream of the test section and air is drawn through the wind tunnel with suction. For Blow-down wind tunnels, however, air is blown down into the wind tunnel by a fan (or centrifugal blower) located upstream of the test section, as the name implies.
