Frame dependence of stationary heat transfer in an inert mixture of ideal gases

An Extended Thermodynamics Model for Blood Flow

“…We expect that the model herein introduced can also describe phenomena in blood flow in which a rapid change in the blood pressure occurs, such as the sudden occlusion of a vessel or rapid initial changes in the fields due to external conditions. Furthermore, from the results obtained for the heat transfer problem in a monoatomic gas or gas-mixtures, see for example [14,15,30,31] and the references therein, we also expect that our model can show more interesting spatial effects also for time-independent phenomena. Indeed, it has been shown that the field equations of RET are able to put in evidence more spatial effects than classical Navier-Stokes-Fourier equations, when a radial symmetry is present or a particular geometry is taken into account.…”

“…In fact, it has been shown that the field equations of RET can describe a range various non-equilibrium phenomena such as light shattering, sound waves, heat waves, structure of shock waves [10][11][12]. RET has been applied to monoatomic gases [10] and mixtures [10,11,14,15] with many interesting results. Recently, RET has been generalized to dense and rarefied polyatomic gases both in the classical [11,12,[16][17][18] and in the relativistic framework [12,19,20], for metal electrons [21,22], to quantum systems [23] and also for biological systems [24][25][26][27], providing relevant results and good agreement with experimental data.…”

An Extended Thermodynamics Study for Second-Grade Adiabatic Fluids

“…In fact, it has been shown that the field equations of ET can describe a range of various non-equilibrium phenomena such as light shattering, sound waves, heat waves and structure of shock waves [1][2][3]. ET has been applied, with many interesting results, to monoatomic gases [1] and mixtures [2][3][4], showing in particular the possibility of describing the thermal-diffusion effect. Recently, ET has been generalized to dense and rarefied polyatomic gases both in the classical [2,3,5] and in the relativistic framework [6][7][8], with respect to metal electrons [9], quantum systems [10], graphene [11], biological models [12][13][14], blood flow [15,16], heat transfer in different symmetries [17] and gas bubbles [18,19], providing in all cases relevant results.…”
