When stress is removed dilatant system
|
Detailed explanation-1: -A significant amount of research has been done into some of the applications of dilatant fluids, including body armor. Pseudoplastic fluids are shear thinning fluids, the opposite. The viscosity of these fluids decreases as the shear rate increases.
Detailed explanation-2: -Fluid Mechanics In shear thickening fluids the viscosity increases as stress increases [20]. An example of dilatant fluid is sand in water. On the other hand, when viscosity decreases when stress increases, the fluid is called pseudoplastic fluid. An example of pseudoplastic fluid is blood.
Detailed explanation-3: -9.5. Pseudo-plastic fluids are also referred to as shear-thinning fluids. The viscosity of these fluids will decrease with increasing shear rate. Therefore, for these fluids, the exponent Eq. 9.4 is n < 1.
