Bingham fluid definition
WebExamines the kinematics and dynamics of the flows of fluids exhibiting a yield stress. Carefully describes the continuum mechanics behind the constitutive equations. Includes … Though the exact cause of shear thinning is not fully understood, it is widely regarded to be the effect of small structural changes within the fluid, such that microscale geometries within the fluid rearrange to facilitate shearing. In colloid systems, phase separation during flow leads to shear thinning. In polymer systems such as polymer melts and solutions, shear thinning is caused by th…
