| Abstract: | In this paper,a water analog for intake swirl was induced,which simulated the 1150 G single cylinder engine.A swirler was designed by authors to induce intake swirl in a 4valve non-swirl intake port engine.At the same time,Particle Image Velocimetry(PIV) was used to measure the flow fields induced by the swirler in the analog in order to understand the characteristics of the intake swirl. |
