CFD MODELING OF MODULAR POULTRY BREEDING

Abstract

Intensive poultry farming in industrial conditions is carried out mainly in rooms equipped with mechanical ventilation systems. The frequency of body heat stress is constantly increasing due to poor regulation of microclimate parameters, which affects the productivity of birds. Infrared heating systems can be an alternative to traditional heating systems for poultry houses. The purpose of the study is to modernize the method of keeping poultry based on the principle of its sectional breeding. For high-quality and simultaneous breeding of different ages of poultry a modular keeping is offered. The heating system of module is a panel infrared heater. It is intended for local heating of technological area. Design dimensions of the module were determined for reasons of qualitative course of technological process, namely the stocking density of poultry. For a better representation of temperature regime in the module CFD modeling was performed. Fields of velocities, pressures and temperatures were obtained. The air temperature near poultry in the module reached 18.6 ºC, and the average velocity did not exceed 0.75 m/s.
