Abstract:
On the basis of the single phase PTV-PIV investigation, solid-liquid two phase flow field particle image velocimetry technique was studied in this paper. Specially processed Al 2 O 3 powder of 5 μ m was taken as liquid phase tracer, millet of 1.5mm in diameter and 1.265kg/m 3 of density was taken as particle tracer. They were scattered in the circulating water channel to form the experimental two phase flow field. Laser sheet was obtained by using a 45mW He-Ne laser source and a series of mi...
