| Abstract | ||
| Ventilation systems for poultry and livestock farming are methods of producing man-made wind (artificial wind). The wind produced from the exhaust air of these ventilation systems could be used to generate electrical energy using wind turbines. In this research, a ventilation energy recovery system for poultry houses was investigated using a Horizontal Axis Wind Turbine (HAWT). The performance of the ventilation system is very important as affected by any obstacle specially when placing the wind turbine in front of the extractor fan. Which could have a negative effect on the system. For executing this research, a primary study was confirmed to examine the effect of obstacles on the ventilation system performance of the (extractor fan rotating speed, its consumption of electrical current, and the static pressure inside the poultry house). The extractor fan shutter blades have been used as obstacles to obtain different blockage percentages. The blockage percentages were zero (full open), 25%, 50%, 75% and 100 % (full closed). Also, the mean air velocity profile for the extractor fan was determined to select where to locate the wind turbine in front of the extractor fan. To harness the energy of the extractor fan exhausted air, the turbine is located in the most proper place in front of the extractor fan. For the propeller diameter for the extractor fan (1270mm) and the rotor diameter for HAWT (1130mm) nearly match each other, so HAWT is placed at the center line of the extractor fan. The turbine tested at distances 10, 20 and 30cm from the extractor fan. These experiments studied the effect of wind turbine placement on extractor fan rotation speed, its required current and the static pressure inside the experimental room. | ||
