1. IMPLEMENTAÇÃO DA TÉCNICA DE FOTOACÚSTICA DE CÉLULA ABERTA PARA OBTENÇÃO DA DIFUSIVIDADE TÉRMICA DE METAIS
The photo-acoustic technique has become a standard photo-thermal method for carrying out diverse studies on solids materials. Photo-thermal phenomena in solids results from a combination of thermal expansion, thermal diffusion, and thermo-elastic bending effects and can be obtained by c k . r a = where k is the thermal conductivity, r is the density, and c i
