Viability of basic heterogeneous nucleation studies with thermally diffusive condensation particle counters.

ABSTRACT:

Hypothesis

While the lack of efficient tools yielding controllable uniform supersaturations (S) has delayed basic experimental heterogeneous nucleation studies, common diffusive condensation particle counters (DCPCs) would fill this gap if their present substantial S-variation could be minimized.

Analysis

For an initially saturated vapor in two-dimensional (2D) parabolic flow, with discontinuous wall temperature change from T_s to T_c, we calculate the spatial S(x,y) distribution, including the curve S_max(Ψ) of maximal supersaturations versus streamline Ψ. Activation probability curves P(T_s,T_c) are also calculated assuming that nucleation goes from zero to 100% at a critical supersaturation S*.
