STUDY IN TRANSIENT REGIME BY ANALYTICAL METHOD OF THERMAL TRANSFER THROUGH AN INSULATING MATERIAL BASED ON TYPHA AND TWO-DIMENSIONAL (2D) CLAY: INFLUENCE OF THE THERMAL EXCHANGE COEFFICIENT ON THE FRONT FACE

In this study, we propose an analytical method of heat transfer for the determination of temperature and heat flux density of a typha-clay material. The expression for the temperature and the heat flux density are obtained from the resolution of the heat equation. The influences of the exchange coefficient at the front face and of the depth in the material are highlighted in the transient dynamic regime in two dimensions.
