Study by Analytical Method of Transient Regime of Thermal Transfer Through a Insulation Material Tow-Plaster - Influence Coefficient of Thermal Exchange

ABSTRACT Heat transfer in transient regime through a tow-plaster insulation is modeled from the analytical method. Reduced variables of space and time are used; variables separation method is applied. Ambient temperature is assumed to be identical at both sides subjected to climatic contraints. Variables heat exchange coefficients are used to minimize thermal exchanges at the level of a side; which virtually equals a cooled side relative to the other side. Evolution curves temperature and heat flux density in time and space function were used to validate method of resolution. Influences of heat exchange coefficient of heat flux are highlighted.
