DENSE CARRIER GAS EFFECT IN VAPOR-PHASE NUCLEATION

By simple Monte Carlo simulation it is demonstrated that the capture o f vapor molecules by a drop is affected by a dense background gas far from the Knudsen regime, and deep within the free molecule regime. The corresponding effect on steady-state nucleation is considered. For se veral representative examples the slopes of critical supersaturation v s carrier gas pressure are obtained and compared with experimental dat a.
