| Abstract: | The selection and supply of tracing particles are often critical for the quality and feasibility of particle image velocimetry (PIV) measurements. A new type of particle generator with a Laskin nozzle is also discussed in detail. When the generator is used in measuring the in-cylinder flow field of an optic engine, lots of seeding particles with good flow-following ability and the light scattering characteristics are made,and the PIV result is very good. |
