Numerical study of flow-induced pulsations in pipe systems with closed branches
conference paper
In this work, a numerical technique based on two-dimensional incompressible computations and vortex sound theory is applied to investigate the flow-acoustic interaction in T-joints, which can lead to resonances in piping systems with closed side branches. The impact of aspects such as the flow direction and edge geometry is analyzed. In spite of the fact that the CFD simulations have a low-Reynolds number, the numerical results are consistent with experimental observations available in the literature, which confirms that the method can be useful for engineering applications, as it provides physically meaningful information at a low computational cost.
