ALVES DAMASCENO, Flávio et al. Evaluation of a Heating System in Poultry Houses Using a CFD Model. Rev. Fac. Nac. Agron. Medellín [online]. 2014, vol.67, n.2, pp.7311-7319. ISSN 0304-2847.  http://dx.doi.org/10.15446/rfnam.v67n2.44178.

The objective of this study was to adapt and validate a computer model using the Computational Fluid Dinamics (CFD), in the prediction of temperature and air speed in a duct distribution system coupled to a heating furnace that is used in typical poultry houses in tropical and subtropical countries. The validation of the model with experimental data was satisfactory, presenting normalized mean square error NMSE values of 0.25 and 0.02 for air temperature and air speed, respectively. The results evidenced that the proposed model is adequate for predicting the air speed and temperature for this type of system, and could be used to improve the efficiency of the distribution of heat inside and around air ducts using different air speeds, types of materials and dimensions.
