Abstract

Highlights: A revised/implemented version of the slim and fat theoretical models is presented. The correlation is valid for Al foams with fluid saturating media. The Mean Squared Error between the experimental and predicted values is very low. Abstract: From the database collected by Ranut (2016), we show that the modified cubic lattice ( MCL ) is capable to predict without fitting parameters the maximum and minimum of the effective thermal conductivity ( ETC ) of the open cell foam. Based on these theoretical upper and lower bounds ( λ eff, max and λ eff, min ), we propose a simple correlation in order to estimate the ETC. This correlation gives a relative low standard deviation between calculated ETC and experimental data, with the majority of ETC data lying in the ±12% region.
