WebbThe axial fan has 4 blades with outlet diameters of 100 mm and is located near the centre of the air inlet hole. Figure 4 Location of the axial fan inside the evaporator cover. A no-slip boundary condition is defined at the walls, pressure inlet, and pressure outlet. Webb13 juli 2024 · When the obstacle is closer to the fan, the strong swirl flow causes a negative pressure region between the fan and the obstacle, reversing the flow direction. This phenomenon is caused by the diffuser effect of the outward flow and the increase in pressure by acting as a multiblade centrifugal fan. t-shirt hugo boss
