Abstract
The effect of piston motion on the incylinder swirling flow for a low speed, large two-stroke marine diesel engine is studies using the stereoscopic PIV technique. The measuremenrs are conducted at 5 cross sectional planes along the cylinder length and at piston positions covering the air intake ports by 0%, 25%, 50% and 75%. The resulting swirling flow decays downstrams the bulk direction and variation in Reynolds number has only effect in terms of magnitud. When the piston translates towards the top-dwad-centra, it gradually starts closing the intake ports. The tangential velocity profile changes fraomRankine/Burges vortes to forced vortex and exial velocity profile changes from wake-like to jet-like and then again to wake-like profile.
