Ostwald de waele equation
Webequation. We introduce the flow parameters in the software where the law of (Ostwald de waele) is defined rheological for the non-Newtonian fluid of index n and consistency K; … 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 the …
