90˚ 분기덕트에서 분기부의 내ㆍ외벽의 속도분포

The flow characteristics in a bifurcated duct are investigated experimentally. Physical properties such as mean velocity vectors and total pressure distributions are obtained for three different Reynolds numbers(578, 620, 688) using PIV measurements and CFD analysis. Also, dividing duct 90° were selected for study. The results of this study would be useful to the engineer in designing the flow systems for heating, ventilation, air conditioning and wastewater purification plants.
