Numerical Simulation of Heat Transfer through Uniform Multilayer Walls using ANSYS

Abstract

The paper presents a study on modelling the main heat transfer parameters through opaque building elements. The need for models to assess the thermal behavior of a building has increased greatly in recent years, primarily to allow a more accurate determination of the energy consumption of buildings to evaluate the performance of heating systems. In recent times, mathematical models and software have been implemented to obtain simulations that are very close to the real functioning of the main components of buildings. The present article consists in modeling a multi-layer homogeneous wall, which separates the interior space of an enclosure (rooms) from the outside environment. The article aims to carry out a series of simulations on the structure of a non-homogeneous multilayer wall using the ANSYS program. The simulations have been performed highlight how the values vary (both numerically and graphically) for a series of characteristic parameters such as heat fluxes, temperatures, convection coefficients. The values of the parameters obtained with the ANSYS program were also compared with those obtained by classical numerical calculations.
