나선형 흡기포트에 의한 cylinder내의 편심 선회 유동특성에 관한 연구

This experimental study was mainly investigated on the eccentric swirl flow characteristics in the cylinder by a helical intake port. LDA system was utilized for the measurement of velocity fields and data were treated by an on-line computer analyzing system. Mass flowrate and angular momentum were calculated with respect to axial distance. As the results from this experiment there is a recirculation zone in the region of the cylinder head and decreases with axial distance. In the calculation of angular momentum in the region of cylinder head using the measured velocity profiles, flowrate must be accurately calculated.
