A dual inlet flow wind power generating system is disclosed having two inflow chambers directing air flow into a common turbine. In one embodiment, a second phase of air flow directly impinges on the air blades of the turbine to provide multi-phased air flow with enhanced power generation. Two inflow chambers may be configured on either side of the common impingement chamber and the system may be configured around a vertical axis. Additionally, air deflectors in one or more chambers may direct flow into a flow tube and may be configured as a positive flow vortex inducer. A negative flow vortex inducer is also described, whereby air is directed by air deflectors to reduce the pressure at the outlet end of a flow tube. In another embodiment, a dual outlet flow system is described having a single inflow chamber and two impingement chambers for second phase air flow.
