Improvement of the photoacoustic response in thermal diffusivity measurements

An alternative photoacoustic cell configuration for the determination of the thermal diffusivity (α), at room temperature, for solid materials is presented. The method is based on the use of two identical photoacoustic chambers, inside both of them, a metallic foil thermally thin is used to transfor...

Arreglo fotoacústico Respuesta fotoacústica Difusividad térmica Celda fotoacústica Modelo de Rosencwaig y Gersho An alternative photoacoustic cell configuration for the determination of the thermal diffusivity (α), at room temperature, for solid materials is presented. The method is based on the use of two identical photoacoustic chambers, inside both of them, a metallic foil thermally thin is used to transform the light energy to heat energy. A Reference material placed parallel to a study material allows to relate the thermal properties of the materials used as support in the photoacoustic chambers of the experimental arrangement presented here. The ratio between experimental and theoretical photoacoustic amplitudes is realized to validate a proposed mathematical model. Se presenta una configuración alternativa de celda fotoacústica para la determinación de la difusividad térmica (α), a temperatura ambiente, para materiales sólidos. El método se basa en el uso de dos cámaras fotoacústicas idénticas, al interior de las cámaras en la parte central, una lámina térmicamente delgada es propuesta para transformar la energía luminosa en energía calorífica. Un material de referencia colocado de manera paralela a un material de estudio en la parte posterior del material térmicamente delgado permite relacionar las propiedades térmicas de estos materiales. Se efectúa la razón de amplitudes de señal fotoacústica con el modelo matemático completo contra el modelo propuesto para cobre vs acero, oro vs plata y granito vs mármol obteniendo un error máximo de 3% al emplear el modelo propuesto en lugar del modelo completo. 2020-12-15 2021-06-03T03:52:17Z 2021-06-03T03:52:17Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://recit.uabc.mx/index.php/revista/article/view/16 10.37636/recit.v34196205 https://hdl.handle.net/20.500.12930/6975 spa https://recit.uabc.mx/index.php/revista/article/view/16/182 https://recit.uabc.mx/index.php/revista/article/view/16/185 https://recit.uabc.mx/index.php/revista/article/view/16/184 Copyright (c) 2020 David Gasca-Figueroa, Micael Gerardo Bravo-Sánchez, Adriana Guzmán-López, José Guadalupe Zavala-Villalpando, Francisco Javier García-Rodríguez http://creativecommons.org/licenses/by/4.0 application/pdf text/html text/xml Universidad Autónoma de Baja California REVISTA DE CIENCIAS TECNOLÓGICAS; Vol. 3 No. 4 (2020); 196-205 REVISTA DE CIENCIAS TECNOLÓGICAS; Vol. 3 Núm. 4 (2020); 196-205 2594-1925
