- W2189163906 abstract "Determining the constitutive behavior of complex ∞uids (e.g., granular materials, pasty ∞uids) remains a delicate task. We present a general method that makes it possible to derive the bulk constitutive relation ?b = F(„u;h) from ∞ume experiments, where ?b, „, and h denote the bottom shear stress, mean velocity, and ∞ow depth, respectively. Indeed, whenever a steady uniform regime is achieved, it is possible to relate the bottom shear stress, the ∞ow depth, and the velocity. Then, after simple algebraic manipulations, we obtained a simple and systematic method to glean information on the rheological behavior. We applied this method to laboratory data obtained with dry granular ∞ows and showed that difierent constitutive relations can be used to describe the same data. We found that a generalized Coulomb relation in the form ?b = „aeb, with aeb the bottom normal stress and „ / („u=h 3=2 ) 1=5 the bulk friction coe‐cient, ofiers a convenient representation of the rheological behavior for a wide range of ∞ow conditions and is supported by theoretical arguments. However, this relation cannot explain the constancy of the front velocity observed experimentally. Another relation in the form ?b = „aeb with „ / „ u 1=5 performs better for steep slopes or when there is a ∞ow-depth gradient, is in good agreement with the data available to date, but is more di‐cult to understand from a rheophysical point of view." @default.
