Abstract
Understanding the vibration of tubes subjected to an internal liquid-gas mixture is of primary importance to improve the design of heat exchangers. Consequently, a large amount of experimental research has been performed in the past decades. Although an extensive number of numerical investigations have been published more recently, most of these papers do not focus on the effect of conditions applied at the fluid domain boundaries. In the current paper it is shown that these boundary conditions can have an important effect on both the stability of the obtained flow solution and on the force exerted on the surrounding tube. The current work aims at correctly predicting the forces on a horizontal 90° bend that was investigated experimentally by Belfroid et al. (2016). The forces exerted on the bend are directly related to the presence of liquid slugs coming into the bend. In the last part of this research, a finite element model for the structure of the pipe is presented.
