Classical-Nucleation-Theory

Simplified single-component classical nucleation rate (Eq. 11.47) from Seinfeld & Pandis (2006), Chapter 11. Computes only the steady-state nucleation rate J from the Zeldovich pre-exponential factor and the free-energy-barrier exponential. Use this component when the critical-cluster properties (i*, r*, ΔG*) are not needed; see the Nucleation component for the full coupled system.

Critical cluster properties for classical homogeneous nucleation theory following Seinfeld & Pandis (2006), Chapter 11, Equations 11.27, 11.35, 11.52, and 11.53. Computes the dimensionless surface tension parameter (theta), critical cluster size (i*), critical radius (r*), and free energy barrier (ΔG*) as purely algebraic functions of temperature, saturation ratio, surface tension, and molecular volume. Use this component for parameter sensitivity studies or when the full nucleation rate (ClassicalNucleationRate) is not needed.

Full coupled homogeneous nucleation system following classical nucleation theory from Seinfeld & Pandis (2006), Chapter 11. Derives saturation ratio and monomer concentration from partial pressures, then computes critical cluster properties (size, radius, free-energy barrier) and the nucleation rate J. Use this component when the full coupled system is needed; see ClassicalNucleationRate for a lighter variant that takes S and N_1 as direct parameters.
