Multiphase fluid structure interaction in pipe systems with multiple bends
conference paper
Two-phase flow occurs in many situations in the process industry. Under certain circumstances this can be a source of flow-induced vibration forces. Although the occurrence of such forces is well known, not much is known about their magnitudes. Previously a set of experiments was carried out at small scales (6 mm and 25 mm diameter). In these experiments the dynamic forces on bends and T-joint structures were measured and simple estimation models where setup. In these experiments only fully developed flow was used and a single geometrical component (bend or T-joint) [1][2][5][9]. In this paper a set of experiments are discussed in which the previous experiments are repeated at 4” scale. Dynamic forces and pressures are measured at the bends. Furthermore the upstream flow condition was verified visually. The results are compared to the previous small scale experiments and a scaling rule has been derived.
