Analogical Modeling and Numerical Simulation for Sintering Phenomena

In this paper the authors propose an approach for analogical modeling and numerical simulation of the phenomena of sintering, taking into account different cases depending on the type of energy used in the process of aggregation and the nature of the material powder, using a software which simulates the propagation and the control of the temperature. Many physical phenomena encountered in science and engineering can be described mathematically through partial differential equations (PDE) and ordinary differential equations (ODE) such as propagation phenomena, engineering applications, hydrotechnics, chemistry, pollution a.s.o. There may be situations when the exact establish of the analytical solutions becomes difficult or impossible for arbitrary shapes. In these cases the determination of some approximant solution through experimental methods, that have to verify with acceptable errors, the PDE expression specified to the studied phenomenon, is justified.
