Asymptotic relation between the temperature and heat flux at a surface for large times in problems with moving boundariesNo Abstract available for this article.doi:10.1007/BF00832609Yu. I. BabenkoKluwer Academic Publishers-Plenum PublishersJournal of Engineering Physics...
relation of vectors in different coordinate system, and thermal conductivity tensor due to temperature scalar field is not changed in the coordinate transformation; we transform thermal conduction equation of rectangular Cartesian coordinate into curvilinear orthogonal coordinates, and draw the conclusion that...
Heat flux, also known as thermal flux, is a term used to express an amount of energy transferred from one place to the other in the form of heat. Heat, the energy associated with the temperature of an object, travels from high temperature to low temperature. Measuring this heat flux with...
Numerical simulations is a good mean to predict these effects in relation with the process parameters but the numerical models need input data such as the value and shape of the heat flux entering the workpiece. In order to estimate this flux, the temperature measurement is necessary but has ...

Later, Tzou8 proposed a dual phase lag (DPL) model by introducing the phase lag of heat flux which is the time delay due to the fast transient effect of thermal inertia. The conduction relation between heat flux vector and temperature gradient can be expressed as $$ \vec{q}\left( {\vec...

Assuming that the absorbing layer is optically thick, and applying the proper the boundary condition to the continuity of the heat flux and the temperature rise at each interface for both the out of plane and in plane configuration, the solutions to Eq. (24) can be obtained with the help ...

To estimate the vertical heat flux, one might have expected Eq. (9.19a) to be function of a vertical turbulent-transport velocity wT times the temperature difference. But for this first-order closure, wT is parameterized as CH|V|, where it is assumed that stronger winds near the ground gen...
