Revising the Fuchs “Boundary Sphere” Method

  • Vladimir Smorodin
Conference paper

The Fuchs “boundary sphere” method used in theory of aerosol coagulation and condensation in the transition Knudsen regime (0.1 ≤ Kn ≤ 10) is critically analyzed. Based on the Poisson-type model of Brownian motion of colliding particles and a “probabilistic theorem”, we demonstrate that the Knudsen layer near the “sphere of influence” is characterized with a finite probability to find moving particles there, if space is isotropic. Therefore Fuchs’ hypothesis about “vacuum” in the Knudsen layer is not physically correct.
