The Herschel–Bulkley fluid is a generalized model of a non-Newtonian fluid, in which the strain experienced by the fluid is related to the stress in a complicated, non-linear way. Three parameters characterize this relationship: the consistency k, the flow index n, and the yield shear stress . The consistency is a simple constant of proportionality, while the flow index measures the degree to which the fluid is shear-thinning or shear-thickening. Ordinary paint is one example of a shear-thinning fluid, while oobleck provides one realization of a shear-thickening fluid. Finally, the yield stress quantifies the amount of stress that the fluid may experience before it yields and begins to flow.

  • El fluido de Herschel-Bulkley es un modelo generalizado de un fluido no newtoniano, en el que la tensión experimentada por el fluido se relaciona con el deformación de una manera complicada y no lineal. Tres parámetros caracterizan esta relación: la consistencia k, el índice de flujo n y el esfuerzo de cizallamiento . La consistencia es una simple constante de proporcionalidad, mientras que el índice de flujo mide el grado en que el fluido se está adelgazando o espesando. La pintura común es un ejemplo de un fluido que adelgaza al cizallamiento, mientras que el fluido no newtoniano proporciona una realización de un fluido que espesa al cizallamiento. Finalmente, el límite elástico cuantifica la cantidad de tensión que puede experimentar el fluido antes de que ceda y comience a fluir.
