The dynamic behaviour of periodic thermodiffusive multi-layered media excited by harmonic oscillations is studied. In the framework linear elasticity, laminates, whose elementary cell composed an arbitrary number layers, are considered. generalized Floquet-Bloch conditions imposed, and universal dispersion relation composite obtained means approach based on formal solution for a single layer to...

Long range fluctuations of the order parameter affect thermodynamic as well as transport properties in the critical region. The values of transport coefficients near a critical point are typically enhanced compared to the values in the classical region far away from a critical point. Asymptotically close to a critical point, the critical enhancements obey power laws with universal critical expo...

We present the thermodiffusion, molecular diffusion and Soret coefficients of several binary and ternary mixtures of DCMIX project. All measurements were carried out at 25oC and two experimental techniques have been used such as the thermogravitational column technique (TGC) and the Sliding symmetric Tubes technique (SST). In addition the thermophysical properties of analysed mixtures have been...

In this paper, a novel mathematical—physical model of the generalized elasto-thermodiffusion (hole/electron interaction) waves in semiconductor materials is studied when hyperbolic two-temperature theory two-dimensional (2D) deformation taken into account. Shear (purely transverse) are dissociated from remainder motion and remain unaffected by external fields. The coupled system partial differe...

We consider the Bresse beam with thermodiffusion effects act on bending moment and axial force together. An exponential stability is obtained in case of equal speeds propagation. Otherwise, a polynomial proved. Using frequency domain method together some multiplier techniques, we prove these results.
