Abstract:
This article aims to study the existence of solutions for a non-isothermal
Navier-Stokes-Allen-Cahn system with thermo-induced coefficients.
The system can be considered as a model describing the motion of a mixture of
two viscous incompressible fluids with viscosity, thermal conductivity and
interfacial thickness being temperature-dependent.
This is a more general system than the previous ones considered in the literature,
involving temperature dependence on all main coefficients.
The strong non-linear couplings between those equations because of the temperature
dependence brings new mathematical difficulties that only allows working in two
dimensions.
