  • Monte-Carlo calculation of the primary H atom yield in liquid water radiolysis: effects of Radiation Type and temperature
    Chemical Physics Letters, 2001
    Co-Authors: Jintana Meesungnoen, Jean-paul Jay-gerin, Abdelali Filali-mouhim, Samlee Mankhetkorn
    Abstract:

    Abstract Monte-Carlo simulations are used to calculate the primary yield of hydrogen atoms (GH ) of water radiolysis versus linear energy transfer (LET) up to ∼100 keV/μm, at 25°C and 300°C. The GH values calculated at 25°C using protons show a maximum near 6.5 keV/μm before decreasing steeply at higher LET. At 300°C, GH remains constant below ∼7 keV/μm, while at higher LET it decreases faster than do its corresponding 25°C values. For different Radiation Types (protons, 2 H + , 4 He 2+ , 7 Li 3+ , and 12 C 6+ ) of equal LET>10 keV/μm, GH increases as the incident ion velocity increases. The results compare generally well with experiment.

  • Radiative effects for some bidimensional thermoelectric problems
    Advances in Nonlinear Analysis, 2016
    Co-Authors: Luisa Consiglieri
    Abstract:

    AbstractThere are two main objectives in this paper. One is to find sufficient conditions to ensure the existence of weak solutions for some bidimensional thermoelectric problems. At the steady-state, these problems consist of a coupled system of elliptic equations of the divergence form, commonly accomplished with nonlinear Radiation-Type conditions on at least a nonempty part of the boundary of a

  • Explicit estimates for solutions of nonlinear Radiation-Type problems
    Acta Mathematica Sinica English Series, 2015
    Co-Authors: Luisa Consiglieri
    Abstract:

    We establish the existence of weak solutions of a nonlinear Radiation-Type boundary value problem for elliptic equation on divergence form with discontinuous leading coefficient. Quantitative estimates play a crucial role on the real applications. Our objective is the derivation of explicit expressions of the involved constants in the quantitative estimates, the so-called absolute or universal bounds. The dependence on the leading coefficient and on the size of the spatial domain is precise. This work shows that the expressions of those constants are not so elegant as we might expect.

  • Radiative effects on the thermoelectric problems
    arXiv: Analysis of PDEs, 2013
    Co-Authors: Luisa Consiglieri
    Abstract:

    There are two main directions in this paper. One is to find sufficient conditions to ensure the existence of weak solutions to thermoelectric problems. At the steady-state, these problems consist by a coupled system of elliptic equations of the divergence form, commonly accomplished with nonlinear Radiation-Type conditions on at least on a nonempty part of the boundary of a $C^1$ domain. The model under study takes the thermoelectric Peltier and Seebeck effects into account, whose describe the Joule-Thomson effect. The proof method makes recourse of a fixed point argument. To this end, well-determined estimates are our main concern. The paper is in the second direction for the derivation of explicit $W^{1,p}$-estimates $(p>2)$ for solutions of nonlinear Radiation-Type problems, where the leading coefficient is assumed to be a discontinuous function on the space variable. In particular, the behavior of the leading coefficient is conveniently explicit on the estimate of any solution. This regularity result is sufficiently general to contribute to other problems, in which the dependence on the values of the involved constants is essential, instead of the problem under study only.
