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… WebJul 25, 2024 · BINGHAM PLASTIC AND HERSCHEL BULKLEY FLUID - YouTube This video is about Bingham Plastic & Herschel-Bulkley fluid.
