| Abstract: | Based on the dimensional analysis, resistance coefficients of spherical particles to Bingham fluid in laminar flow region, transition region and fully developed turbulent flow regions are derived respectively. A systematical experimental study on settling velocity of steel balls in slurry with different sediment concentrations is conducted and comprehensive discussions are presented. Formulae proposed by the authors are checked with experimental data from various sources. |
