Theoretical analysis of thermophoretic experimental data
Abstrak
Thermophoresis is a transport phenomenon induced by a temperature gradient. Very small objects dispersed in a fluid medium and in a temperature gradient present a non homogeneous steady density. Analysing this phenomenon within the theoretical scenario of non interacting Brownian motion one can assume that those particles are driven by a spatially dependent mechanical force. This implies the existence of a potential which was derived in a previous work. From this potential the qualitative properties of the force and the Soret coefficient were obtained. Nevertheless a quantitative correlation between the theory and the experimental data were not consistently proved. Here it is presented a methodology to match this theory with the experimental data, which it is used to analyse the experimental information of sodium docecyl sulfate (SDS) micelles.
