Obtaining flow curve for viscoplastic fluids through inclined open-channel apparatus
(Springer, 2021-05-01)
Non-Newtonian fluids are commonly seen in industrial processes, such as those of the oil and mining industry, and in natural flows, like dam ruptures, landslides or mud flows. The hydrodynamic modeling of such processes/phenomena ...

Estudo teórico-experimental em via de determinação de lei de atrito em escoamentos de fluidos hiperconcentrados
(Universidade Estadual Paulista (Unesp), 2003-07-30)
Em função da concentração de material sólido, misturas resultantes de argila e água conferem, via de regra, propriedades não-Newtonianas. Essa concentração passa a variar com a granulometria e a composição do mineral do ...
