Delta-pulse solution in Zener viscoelastic model
Andrea Mentrelli, Juan Luis Gonzalez-Santander, Francesco Mainardi
We derive the integral representation of the solution for the propagation of a delta-pulse (impulsive wave) in a semi-infinite, homogeneous, linear viscoelastic medium governed by…
A Novel ES-BGK Model for Non-Polytropic Gases with Internal State Density Independent of the Temperature
Takashi Arima, Andrea Mentrelli, Tommaso Ruggeri
A novel ES-BGK-based model of non-polytropic rarefied gases in the framework of kinetic theory is presented. Key features of this model are: an internal state density function depe…
Energy dissipation in viscoelastic Bessel media
Ivano Colombaro, Andrea Giusti, Andrea Mentrelli
We investigate the specific attenuation factor for the Bessel models of viscoelasticity. We find that the quality factor for this class can be expressed in terms of Kelvin function…
A new approach to the thermodynamics of scalar-tensor gravity
Valerio Faraoni, Andrea Giusti, Andrea Mentrelli
We discuss and expand a new approach to the thermodynamics of scalar-tensor gravity and its diffusion toward general relativity (seen as an equilibrium state) proposed in a previou…
Orbits in a stochastic Schwarzschild geometry
R. Casadio, A. Giusti, A. Mentrelli
We study geodesics in the Schwarzschild space-time affected by an uncertainty in the mass parameter described by a Gaussian distribution. This study could serve as a first attempt…
Asymptotic-Preserving scheme for a strongly anisotropic vorticity equation arising in fusion plasma modelling
Andrea Mentrelli, Claudia Negulescu
The electric potential is an essential quantity for the confinement process of tokamak plasmas, with important impact on the performances of fusion reactors. Understanding its evol…
