The governing equations were discretized and solved using the fi nite volume method on unstructured triangular meshes; and a coupling scheme for the fl uid and solid heat transfer problems was proposed. The computational model was validated using two test cases in which local and average Nusselt numbers are reported in the literature. The local Nusselt number for each apple was obtained during one hour of air cooling as a function of the Reynolds number. Nusselt number and temperature distribution were found to vary in the apples due to the conjugate behavior of the problem. The conjugate approach showed itself to be a powerful tool for optimizing the convective heat transfer correlations reported in the literature. 2011 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49622365019 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.166 Vol.78 |
