Теоретические оценки теплопроводности сегрегационного льда

Title: Теоретические оценки теплопроводности сегрегационного льда
Title, transliterated: Teoreticheskie ot︠s︡enki teploprovodnosti segregat︠s︡ionnogo lʹda / R.I. Gavrilʹev.
Translated title: Theoretical estimation of thermal conductivity of segregated ice.
Author(s): Gavrilʹev, R. I.
Gavriliėv, R. I.
Date: 2008.
Language: Russian.
In: Kriosfera Zemli. (2008.), Vol. 12(2) (2008)
Abstract: Estimates thermal conductivity of segregated ice, using model of porous ice with open and closed cylindrical pores along heat flow and with spherical bubbles, taking into account additional convective heat transfer by vapour diffusion in air bubbles. Model's basis (frame) consists of continuous body of pure hexagonal ice (ice I). Thermal conductivity calculations based on Maxwell-Rayleigh theory of generalized conductivity produce values much higher that experimental values, probably because of methodological shortcomings in both calculation and experiment. Advocates new methodology free of limitations on layered structure of test medium, and X-ray investigations to determine more precisely the structure of segregated ice.
