A PIV Visualization Study on Static Flow Field Characteristics of Savonius Rotor in Food Production Bases with Different Overlap Ratios

摘要

In this study, the PIV sensor visualization experiments are carried out on Savonius rotor in food production with two kinds of overlap ratios of 0 and 0.2 to study the mechanism of the effects of overlap ratio on static flow field. The static velocity fields in and around Savonius rotor in food production were obtained in the test at four typical azimuth angles of 0°, 35°, 90° and 165°. The test results show that the existence of overlap ratio has large effects on the static flow fields of the rotor in food productions with and without overlap ratio at different azimuth angles.
