Global well‐posedness of 2D nonlinear Boussinesq equations with mixed partial viscosity and thermal diffusivity [PDF]
Mathematical Methods in the Applied Sciences, 2017 In this paper, we discuss with the global well‐posedness of 2D anisotropic nonlinear Boussinesq equations with any two positive viscosities and one positive thermal diffusivity. More precisely, for three kinds of viscous combinations, we obtain the global well‐posedness without any assumption on the solution.

Nonlinear thermal conductivity in gases
Lietuvos Matematikos Rinkinys, 2016 The nonlinear diffusion equation corresponds to the diffusion processes which can occur with a finite velocity. A.J. Janavičius proposed nonlinear equation which describes more exactly the diffusion of impurities in Si crystals in many interesting ...

Numerical solution of a nonlinear integral equation for the determination of the unknown time-dependent diffusivity of radioactive materials [PDF]
Mathematics and Computational SciencesThe thermal diffusion coefficient in radioactive materials is not a constant value, and this makes the heat transfer problem different in such materials and materials that are not homogeneous and have been destroyed or are disintegrating in some way.

Applied Mathematics and Computation, 2010 The authors study a thermal energy storage problem using a linear transformation group approach. The model under consideration is written as \( T^{b}\frac{\partial T}{\partial t}=\frac{1}{r^{m}}\frac{\partial }{\partial r }(T^{n}r^{m}\frac{\partial T}{\partial r})+S(T)\) where \(m=0,1,2\) respectively corresponds to a rectangular, cylindrical or ...

The Proton Distribution Function in Weakly Magnetized Turbulent Plasmas [PDF]
, 1998 We calculate the proton distribution function due to heating by subsonic (Alfvenic) turbulence in a weakly magnetized collisionless plasma. The distribution function is nonthermal.
