Experimental Estimation of Critical Buckling Velocities for Conservative Pipes Conveying Fluid

Conservative pipes conveying fluid such as pinned-pinned (p-p), clampedpinned (c-p) pipes and clamped-clamped (c-c) lose their stability by buckling at certain critical fluid velocities. In order to experimentally evaluate these velocities, high flow-rate pumps that demand complicated fluid circuits...
