COMPUTATIONAL ANALYSIS OF VENTILATION SYSTEMS FOR LIVESTOCK BUILDINGS

THE ENVIRONMENT SURROUNDING CONFINED ANIMALS DIRECTLY AFFECTS THE PRODUCTIVITY OF THE LIVESTOCKINDUSTRY. A GOOD VENTILATION SYSTEM, WHICH CONTROLS THIS ENVIRONMENT, IS ESSENTIAL FOR MANTAINING THE HEALTH AND WELFARE OF ANIMALS AND WORKERS IN THE LIVESTOCK BUILDINGS. HOWEVER, THE DESIGN AND MANAGEMENT OF SUCH A SYSTEM IS A COMPLICATED PROCESS. IT INVOLVES OPTIMIZATION OF VARIOUS GOVERNING PARAMETERS TO OBTAIN THE ACCEPTABLE LEVELS OF AIRFLOW, TEMPERATURE, MOISTURE, DUST, AND NOXIOUS GASES IN THE BUILDING. DISTRIBUTION OF THESE PARAMETERS DEPENEDS ON VARIOUS OPERATIONAL, STRUCTURAL AND ANIMAL RELATED FACTORS AND THEIR COMPLEX INTERACTION WITH THE SURROUNDING. THIS RESEARCH AIMS TO DEVELOP A NUMERICAL SIMULATION MODEL FOR THE ANALYSIS OF HEATING AND VENTILATION SYSTEMS OF THE LIVESTOCK BUILDINGS. ADVANCED TECHNIQUES OF COMPUTATIONAL FLUID DYNAMICS (CFD) WILL BE USED TO SIMULATE THE FULL-SCALE, REAL-LIFE SITUATIONS IN THE BUILDINGS. IN THE SECOND PHASE OF THIS RESEARCH, PHYSIOLOGICAL AND BEHAVIORAL RESPONSE OF THE ANIMALS WILLBE INCLUDED.
