Fig. 1.

The supersaturation surplus S−S∞ for an initial supersaturation of S0=105 and S∞=1. The vertical lines designate the simulation times of 1 min and 1 hr, a total simulation time of 24 hr is presented.

Fig. 2.

The nucleation rates for the three discussed nucleation theories for an initial supersaturation of S0=105. The vertical lines represent the simulation times of 1 min and 1 hr, a total simulation time of 24 hr is presented.

Fig. 3.

The number concentration in dependency of the used nucleation theories are shown. The vertical lines represent the simulation times of 1 min and 1 hr, a total simulation time of 24 hr is presented.

Fig. 4.

The PSDs resulting from the three different nucleation theories after a simulation time of 1 min for S0=105.

Fig. 5.

The PSDs resulting from the three different nucleation theories after a simulation time of 1 hr for S0=105.

Fig. 6.

The PSDs resulting from the three different nucleation theories after a simulation time of 24 hr for S0=105.

Fig. 7.

The relative deviation of the total volume Vtot [defined in Equation (11)] from the initial total volume V0.

Fig. 8.

The supersaturation in dependency of its initial value S0 for the Girshick nucleation theory. The vertical lines represent the simulation times of 1 min and 1 hr, a total simulation time of 24 hr is presented.

Fig. 9.

The number concentration in dependency of the initial supersaturation value S0 for the Girshick nucleation theory. The vertical lines represent the simulation times of 1 min and 1 hr, a total simulation time of 24 hr is presented.
