A thermodynamically consistent quasi-double-porosity thermo-hydro-mechanical model for cell dehydration of plant tissues at subzero temperatures

Abstract Many plant tissues exhibit the property of frost resistance. This is mainly due to two factors: one related metabolic effects, while other stems from structural properties plants leading dehydration their cells. The present contribution aims at assessing impact ice formation on frost-resistant with a focus specifically applied Equisetum hyemale . In this particular case, there an extracellular in so-called vallecular canals and pith cavity, which leads tissue cells avoid intracellular formation, what would be fatal for subsequently whole plant. To address underlying phenomena plant, coupled thermo-hydro-mechanical model based Theory Porous Media introduced as modelling framework. referred quasi-double-porosity nature, since water mobile within intercellular space, but confined space consequently kinematically them. However, mass exchange across cell wall considered. presented numerical example shows strong coupling processes well feature. Finally, it supports experimental finding main location formation.
