Nonisothermal homogeneous nucleation
Classical homogeneous nucleation theory is extended to nonisothermal conditions through simultaneous cluster mass and energy balances. The transient nucleation of water vapor following a sudden increase in saturation ratio is studied by numerically solving the coupled mass and energy balance equations. The ultimate steady state nucleation rate, considering nonisothermal effects, is found to be ...
متن کاملAtmospheric homogeneous nucleation
Atmospheric Chemistry and Physics Discussions This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract We report laboratory observations of H 2 SO 4 and H 2 O homogeneous nucleation made under atmospherically relevant conditions ([H 2 SO 4 ] of 10 6 – 10 7 cm −3 and 287 K)....
متن کاملIgniting homogeneous nucleation.
Transient homogeneous nucleation is studied in the limit of large critical sizes. Starting from pure monomers, three eras of transient nucleation are characterized in the classic Becker-Döring kinetic equations with two different models of discrete diffusivity: the classic Turnbull-Fisher formula and an expression describing thermally driven growth of the nucleus. The latter diffusivity yields ...

متن کاملHomogeneous nucleation of NAD
Activation energies ∆G act for the nucleation of nitric acid dihydrate (NAD) in super-cooled binary HNO 3 /H 2 O solution droplets were calculated from volume-based nucle-ation rate measurements using the AIDA (Aerosol Interactions and Dynamics in the Atmosphere) aerosol chamber of Forschungszentrum Karlsruhe. The experimental 5 conditions covered temperatures T between 192 K and 197 K, NAD sat...
