Air supply characteristics of ejection- permeation fabric air dispersion system

By means of the conservation equations of mass and energy, builds a pressure distribution model of the ejection- permeation fabric air dispersion system, and analyses the variation of internal pressure and air supply characteristics under different structure and supply air rate. The results show that along the flow direction the internal total pressure and internal dynamic pressure decrease and the internal static pressure increases, the diameter of the fabric air duct and the inlet supply air rate have a greater effect on the flow rate of ejection and permeation, and the permeability of fabric has a great influence on the flow rate of ejection.
