Dear all, Our upcoming AM seminar is held Wed 10 May at 1pm in F11 Chemistry Lecture Theatre 4. Our speaker is Noa Kraitzman (Macquarie). Talk details follow below: -------------------------------------------------------------------------------------------------------------------------------------------- Title: Mathematical modelling of sea ice Abstract: In this talk I will delve into the behaviour of sea ice, examining both its microstructure and its effective properties. Firstly, I will introduce a thermodynamically consistent model for the liquid-solid phase change in sea ice that incorporates the effects of salt, using multiscale analysis to derive a quasi-equilibrium Stefan-type problem. Secondly, I will investigate the thermal conduction in sea ice in the presence of fluid flow, using a new Stieltjes integral representation for the effective conductivity and present rigorous bounds on the conductivity obtained through Pade approximates. -------------------------------------------------------------------------------------------------------------------------------------------- An ongoing list of AM seminars is posted here: https://www.maths.usyd.edu.au/u/SemConf/Applied.html See you there, Ian
