Which phenomenon causes non-Newtonian behavior when the Reynolds number drastically increases?

A)Shear thickening via dilatancy
B)Increased boundary layer separation
C)Reduced form drag coefficient
D)Laminar flow profile adjustment

💡 Explanation

Dilatancy results in shear thickening because high shear rates disrupt the layered structure, leading to increased viscosity. Therefore, option A, rather than the others, describes this behavior at greatly increased Reynolds numbers and shear stress conditions.
