The Influence of Inclusion and Porosity on Thermal Conductivity of Metal Matrix Composite using Mathematical Model

The mathematical modelling programme MATLAB was used to examine the effective thermal conductivity of heterogeneous materials, and the results are given in this research. The prediction of metal matrix composite materials' thermal conductivity in relation to different relevant variables such as inclusion size and volume %. Ceramic compounds and non-thermal conductive inclusions are common.It appears that determining the effect of inclusion on the thermal conductivity of heterogeneous materials using standardised tests is challenging. As a result, the created mathematical tool may be used to demonstrate the effect of inclusions on thermal conductivity. For the evaluation of heterogeneous metals, the volume proportion of inclusion has been estimated to be up to 50%. For the thermal conductivity test, metals such as aluminium, iron, magnesium, and zinc were chosen.
