LOW-ENERGY-ION ENHANCED DIFFUSION AT THE SURFACE OF METALS
Radiation enhanced diffusion at the surface of metals has been observed and studied for low-energy nitrogen ions at the surface of copper. The displacement of the target atoms during irradiation creates vacancies and other defects near the surface, thus enhancing the diffusion of implanted materials toward the surface and also into the solid. The mechanism has been studied here by a specia...
متن کاملHorizontal convection is non - turbulent
Consider the problem of horizontal convection: a Boussinesq fluid, forced by applying a non-uniform temperature at its top surface, with all other boundaries insulating. We prove that if the viscosity, ν, and thermal diffusivity, κ, are lowered to zero, with σ ≡ ν/κ fixed, then the energy dissipation per unit mass, ε, also vanishes in this limit. Numerical solutions of the two-dimensional case ...
متن کاملComments on ‘‘A turbulent diffusion model for particle dispersion and deposition in horizontal tube flow’’
An error was found in the paper ‘‘A Turbulent Diffusion Model for Particle Dispersion and Deposition in Horizontal Tube Flow’’ by Mols and Oliemans (1998). The error affected the results presented in the first part of the paper, namely, Figs. 6–11. The objective of this Brief communication is to correct the error providing the proper solution, and to present the main results with the corrected ...

متن کاملTurbulent pair diffusion.
Kinematic simulations of turbulent pair diffusion in planar turbulence with a k(-5/3) energy spectrum reproduce the laboratory results of Jullien et al. [Phys. Rev. Lett. 82, 2872 (1999)]], in particular the stretched exponential form of the probability density function of pair separations and their correlation functions. The root mean square separation is found to be strongly dependent on init...
