A numerical study on natural ventilation promotion and control in experimental house with fluid diode window

Abstract: The objective of this study is to investigate the effects of installing a fluid diode window (FDW) in buildings to promote natural ventilation by controlling ventilation paths. An FDW is a porous plate with an internal structure that provides varying resistance to airflow depending on the flow direction. An FDW was installed in the bathroom of an experimental house to prevent polluted air from flowing into the adjacent multipurpose room during ventilation. Computational fluid dynamics simulations with a steady… Show more

“…According to [15], this shape has similar properties to the diffuser -when the air travels from the narrow channel to open space, the hydraulic losses are much higher than in the other direction. Research [13,14] shows that it is possible to design a part with hydraulic losses strongly depending on flow direction, but this particular air grill doesn't work as intended.…”

“…1a). The device made of many channels in this shapes called the "fluid diode" is being currently tested [13,14]. But the complexity makes it difficult to manufacture it in small size, and those devices usually take shape of large plates placed in window opening.…”
