← ScienceWhich outcome results when the viscosity term dominates in Navier-Stokes equations during fluid flow around a miniature drone's rotor?
A)Velocity profile becomes smooth✓
B)Turbulent kinetic energy increases sharply
C)Pressure gradients amplify non-linearly
D)Overall drag decreases substantially
💡 Explanation
Increased viscosity causes laminar flow because viscous forces dampen inertial forces, promoting the mechanism of viscous dissipation. Therefore, the velocity profile becomes smooth, rather than pressures amplifying, because turbulence is suppressed under increased viscosity.
