Heat waves simulation

This paper deals with one-dimensional simulation of heat waves, which occur in materials affected by pulsed or continuous surface heat source. The mat hematical model is constructed according to the extended hyperbolic heat co nduction (EHHC) theory. Effects of relaxation numbers, surface emissivity, or surface heat convection transfer are discussed. The designed analytical- numerical simulation method is investigated to show special features and be havior of the method. Simulation examples are devoted to numerical oscillat ions and to ways of their minimization. Resulting temperature distributions from simulation experiments are complemented with instructions for use to obtain better accuracy and to suppress undesirable oscillations.
