A note on an invariant for one-dimensional heat conduction
Hamou Sadat, Christian Prax, Vital Le Dez
The main goal of this note is to show that a proposed invariant for one-dimensional heat conduction in dielectrics and metals is nothing than an approximate solution to the Fourier…
On the thermal rectification factor in steady heat conduction
Hamou Sadat, Vital Le Dez
Thermal rectification in heat conduction problems has been extensively studied in planar slabs. Here we consider the rectification problem in planar, cylindrical and spherical geom…
Restitution of the Temperature Field Inside a Cylinder of Semitransparent Dense Medium From Directional Intensity Data
Vital Le Dez, Denis Lemonnier, Hamou Sadat
The purpose of this paper is to obtain the temperature field inside a cylinder filled in with a dense nonscattering semitransparent medium from directional intensity data by solvin…
Meshless method for solving radiative transfer problems in complex two-dimensional and three-dimensional geometries
Cheng-An Wang, Hamou Sadat, Vital Le dez +1
A meshless method is presented to solve the radiative transfer equation in the even parity formulation of the discrete ordinates method in complex 2D and 3D geometries. Prediction…
Radiative heat transfer in a parallelogram shaped cavity
V. Le Dez, H. Sadat
An exact analytical description of the internal radiative field inside an emitting-absorbing gray semi-transparent medium enclosed in a two-dimensional parallelogram cavity is prop…
