← ScienceWhich flow behavior change occurs when a viscous damper's fluid temperature rises under high-frequency load?
A)Increased turbulent flow intensity
B)Decreased damping coefficient appears✓
C)Cavitation erosion rate slows
D)Boundary layer thickness extends
💡 Explanation
A temperature rise lowers the fluid's viscosity; therefore the viscous damping reduces because internal fluid friction (the damping mechanism) diminishes, rather than turbulent intensity rising or cavitation erosion slowing at high frequency.
