Spectroscopic Analysis of Thermal Behaviour of Kapok-Plaster Material in Dynamic Frequency Regime Established

ABSTRACT Thermal exchange phenomena between a wall kapok-plaster and its environment are presented. Study electrical equivalent model was used to show different wall behaviors : for lows pulsation, wall behavess as inductor and resistor in series and opposing the variation of the heat flux density. For high pulsations, material has a capacitive behavior, storing of heat; thermal insulating character is thus considerable. There exists between these two situations a resonant pulsation for which the wall obtains a pure resistive behavior. Keywords: Inductance equivalent- equivalent capacity - Thermal Insulation
