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

The objective of this study is to focus on the influence of local insulating materials in thermal insulation for a well-defined period. The material is a wall consisting of typha and clay. The main objective of this study is to see the behavior of the thermal resistance of the material as a function of the heat exchange coefficient at the front face. The typha and clay wall is modeled by applying the transient analytical method with the two-dimensional heat equation. This analytical resolution of the heat equation allows us to determine the detailed expression of the thermal resistance but also to visualize the curves of evolution of this resistance according to the depth under the influence of the heat exchange coefficient at the front side.
