We consider a nonlinear elliptic-parabolic system which stems from the modelling of heat induction processes in which a sinusoidal electromagnetic field is applied at the boundary of the inductor. The magnetic field satisfies an elliptic equation whereas t ...
In the first part of this work a comprehensive model of the continuous hardening of 3D-axisymmetric steel components by induction heating has been developed. In the model, the Maxwell and heat flow equations are solved using a mixed numerical formulation : ...
In order to quantify the cooling conditions undergone by an ingot during direct-chill (DC) casting, thermocouples were immersed in the liquid pool and consequently entrapped in the solid, thus monitoring the temperature of the metal during its descent. Ass ...
A new technique is presented for the prepn. of DSA type electrodes. In this technique, the precursor is rapidly decompd. on the substrate by treatment in an induction electromagnetic field. The effects of the rapid heating of H2IrCl6.6H2O precursor on Ti s ...
Air conditioning unit for vehicle which is compact and economical, while ensuring simplification of the combination of means for controlling the temperature of different elements of the vehicle. The unit comprises a fan which supplies two conduits placed p ...
A comprehensive three-dimensional mathematical model based upon the Abaqus software has been developed for the computation of the thermomechanical state of the solidifying strand during direct chill (DC) casting of rolling sheet ingots and during subsequen ...
Inverse methods can be used in solidification and related processes for the estimation of boundary conditions or physical properties of materials. For heat flow problems, these methods are based upon a minimisation of the errors between calculated and meas ...
This paper discusses the construction of a dynamic energy balance equation using boundary conditions conventionally defined for a thermodynamic system. With routine modifications, the equation can be applied to a wide variety of engineering systems. The eq ...

Heating of tokamak plasmas up to temperatures of the order of 10 keV (≈ 108 0K) is one of the main subjects in plasma physics research. Much experimental and theoretical effort has been devoted to the improvement of the heating efficiency and to the unders ...
