Fig. 5From: Fluid damping of cylindrical liquid storage tanksDamping ratios \( \kappa \) of the free sloshing oscillation in the 1st axial and circumferential mode for a more slender tank with slenderness \( \alpha_{L} = 1.0 \), a kinematical viscosity \( \nu_{L} = 4.2\; \times \;10^{ - 4} \;{\text{m}}^{ 2} / {\text{s}} \) and a density \( \rho_{L} = 912\;{\text{kg/m}}^{ 3} \) (oil, SAE 30 at 15.6 °C) in dependence of the tank radius R. The damping is size dependent and decays with increasing tank volume. Furthermore the liquid motion at the tank wall dominates the dampingBack to article page
