P9.10Tue 611:23-14:00Entropy production and Onsager’s coefficientsevaluation in the drop evaporation processKostyantyn Cherevko, 1 Andrii Britan, 1 Dmytro Gavryushenko, 1 VolodymyrSysoev, 1 and Galyna Verbinska 11 Kyiv National University, 2(1) Glushkova av. , 03022, Kyiv, UkraineThe diffusive regime of the drop evaporation process is investigated in this work on the basics ofthe fundamental equations of the linear irreversible processes thermodynamics. Therefore the fulldiffusion equation is used to take into account all the peculiarities of the investigated system in thevery beginning of the investigation process. Analytic formulae are obtained for the diffusion flowof vapor and temperature distribution [1] around the droplet. Entropy production function in thedrop evaporation process is found. The method to find Onsager’s phenomenological coefficientsfrom the drop evaporation experiments is proposed.[1] K. Cherevko, D. Gavryushenko, V. Sysoev, Ukr. Phys. J. volume 52, 31, (2007).10
