Abstract

Results of theoretical estimations of effective heat conductivity for fractal-like soot aggregates on the basis of Evans et al. (2008) theory are presented. It is shown that these estimations give an adequate values of this parameter essentially important for calculations of characteristics of photophoretic motion of soot aggregates. Comparison of the developed theory for fractal-like particles photophoresis with experimental data of Karasev et al. (2004) demonstrates high efficiency of the offered approach.
