Aerosol behavior in temperature and concentration gradient fields in nonisothermal tube flow

A general aerosol dynamics equation is derived for nonisothermal steady flow in cylindrical geometry. A scheme for the numerical solution of this equation is presented and its application is illustrated for a practical case incorporating condensation, nucleation, and thermophoresis effects.

Description
Summary:A general aerosol dynamics equation is derived for nonisothermal steady flow in cylindrical geometry. A scheme for the numerical solution of this equation is presented and its application is illustrated for a practical case incorporating condensation, nucleation, and thermophoresis effects. Additionally, the results of the numerical computations are compared with laboratory experimental measurements of changes in aerosol concentrations and size distributions for nonisothermal flow through a horizontal circular tube.
