Description: Bird welfare and comfort is very important inside poultry coops during loading at the farm, transportation and holding at the processing plants, especially during summer and winter months. The microenvironment inside a poultry coop resulting from hot/cold temperatures, relative humidity and heat production leads to complex Multiphysics. In order to deal with multiphysics phenomena involving fluid flow, heat transfer, and humidity within the coops, CFD (Computational Fluid Dynamics) simulations combined with AI (artificial intelligence) models may be helpful to evaluate broiler welfare/comfort under various microenvironments. Computational fluid dynamics simulations were conducted to investigate the combined effects of temperature, RH, air velocity, and heat produced by the birds inside a poultry coop. The enthalpy comfort index (ECI) that relates to temperature, relative humidity was calculated to evaluate the poultry coop welfare that corresponds to bird welfare conditions (comfort; warning; critical; and lethal). The results from CFD simulations were then used in AI through artificial neural networks and Bayesian optimization to estimate the desired parameters required to ensure broiler welfare inside the coops. Several microenvironments within the coops were investigated from CFD simulations and then used AI model to predict the ECI. Results from AI model indicated that reducing the broilers heat production inside the coop along with increasing fan velocity enhances the broiler welfare and the thermal microenvironment.
