THE SIMILITUDE THEORY APPLIED FOR THE STUDY OF THE HEAT TRANSMISSION IN CASE OF THE LASER DEPOSITION

Abstract

: As the real phenomena of the heat transmission may intervene, in proportions which vary from a case to another, the all three modes of propagation, for the description of the global process can use a virtual model similar to the original. The similitude theory, establishing the criterion of the ascertainment of the phenomena of heat convection allows the attainment of some formulas for the determination of α, applicable to any similar case, and the performance of the experiments on models, allowing on a hand to the experiment to be possible, and on the other hand, to be economic.
