The results of a comprehensive experimental study on the creeping sphere motion in Herschel-Bulkley model fluids are reported and discussed in this paper. A series of aqueous solutions of different grades of Carbopol resin have been used to encompass wide ranges of rheological model parameters. In particular, the size and shape of the sheared cavity surrounding a moving sphere and the drag behaviour have been investigated in this study. A laser-speckle tracer method was used to obtain… CONTINUE READING
