The probability distribution for the molecular extension was determined as a function of shear rate, γ˙, for two different polymer relaxation times, τ. (science.sciencemag.org)
The recipe - specific shear rate in mixing and optimized heat treatment with high product velocity achieves the desired product characteristics. (tetrapak.com)
The reason for shear thinning flow behaviour is that an increased shear rate deforms and / or rearranges particles, resulting in lower flow resistance and consequently lower viscosity. (dairyprocessinghandbook.com)
