fan ptot

Figure: Total pressure on a slice for outlet pressure 500 Pa and four times 0.050-0.053 s. One of the fan’s blades is highlighted to make the wheel rotation clearly visible.

fan pblade

Figure: Static pressure on the walls of one of the blades. Outlet pressure 500 Pa, time 0.05 s.

fan graf phi eta 1

Figure: Efficiency of the fan evaluated at the artificial inlet and outlet (“full”) and at the real inflow and outflow (“wheel”). The lines follow the results of the steady-state case for different outlet pressures from 100.5 kPa to 105.5 kPa, whereas the blue points indicate evaluated results for different times of the transient simulation for the given output pressure 100.5 kPa. The darkest blue point is the most recent time step, $ t = 0.21$ s.

fan graf phi psi

Figure: Pressure coefficient of the fan evaluated at the artificial inlet and outlet (“full”) and at the real inflow and outflow (“wheel”). See the explanation text below the previous figure [*] for details.
