Tunable Heat-Flux Rectification in Graded Nanowires in Non-Linear Guyer-Krumhansl Regime
We study Trash Bin heat rectification in composition-graded nanowires, with nonlocal and nonlinear effects taken into account in a generalized Guyer-Krumhansl equation.Using a thermal conductivity dependent on composition and temperature, the heat equation is solved.Introducing a non-vanishing heat supply (as for instance, a lateral radiative heat
