Simulation of winter heat fluxes through a clay wall with added wheat straw using the finite element method

Abstract

This study focuses on the simulation of heat transfer through a brick wall using an experimental model of unfired ceramic bricks with different additions of wheat straw. A digital model of the wall was created using computer software. Using the finite element method, the behavior of the external brick wall of a residential building is analyzed under changing external temperatures and constant internal temperature. The analysis process is divided into two main parts. The first part covers the stationary problem, which determines the temperature distribution in the wall. In the second part, this solution serves as an initial condition for dynamic analysis. This approach allows investigating how the wall responds to heat by analyzing the dynamic temperature distribution, heat flow and stored energy in the wall. The analyzes will serve to improve the energy efficiency and comfort of residential buildings.
