Low Reynolds number capture of small particles on a cylinder by diffusion, interception and inertia at subcritical Stokes numbers: Numerical calculations, correlations, and small diffusivity asymptote

When the particle-to-target radius ratio R and the inverse Peclet number 1/P are small, particle capture by interception and diffusion by cylinders at low Reynolds numbers may be described via Friedlander’s single similarity parameter Π ≡R·P1/3, in the full range 0
