Título : | On the modulation frequency dependence of the photoacoustic signal for a metal coated glass-liquid system |
Palabras clave : | hotoacoustic heat transfer |
Fecha de publicación : | 16-ene-2013 |
Editorial : | Central European Journal of Physics |
Descripción : | We show that the front photoacoustic signal due to a sample consisting of a glass plate with a metal
coated surface, at which thermal waves are generated by periodical light absorption, enhances for certain
modulation frequencies when the other glass surface is covered with a liquid sample. This contradicts the
intuitive expectation based on the assumption that the liquid provides a new channel for heat conduction
thereby decreasing the substrate temperature. Experimental results are shown and the described effect is
explained using a thermal wave interference model. Instituto politecnico Nacional CONACYT |
