Fluid-elastic instability in tube arrays subjected to air-water and steam-water cross-flow
TL;DR: In this paper, experiments were carried out with air-water and steam-water cross-flow over horizontal tubes, and it was found that fully flexible arrays become unstable at a lower flow velocity when compared to a single flexible tube surrounded by rigid tubes.

Fluidelastic instability study on a rotated triangular tube array subject to two-phase cross-flow. Part II: Experimental tests and comparison with theoretical results
TL;DR: In this article, a new formulation of the added mass as a function of the void fraction is proposed, which takes into account the reduction of void fraction around the tubes in a rotated triangular tube array and yields better agreement with the experimental data compared to previous formulations.

Flow-induced vibration of nuclear steam generator U-tubes in two-phase flow
TL;DR: In this paper, a U-tube bundle was used to simulate the innermost region of an actual steam generator for air-water two-phase flow simulation, where the U-tubes and supporting structures were made of Inconel 690 with a diameter of 19.05 mm.

Two-phase flow patterns across triangular tube bundles for air–water upward flow
TL;DR: In this article, the authors presented flow pattern experimental results obtained during two-phase upward flow across a horizontal tube bundle and proposed new predictive methods for transitions between flow patterns based on the flow patterns identified objectively.

Flow-induced streamwise oscillation of two circular cylinders in tandem arrangement
TL;DR: In this article, free-oscillation testing of two tandem circular cylinders was carried out in a wind tunnel, where one cylinder was elastically supported so as to allow it to move in the streamwise direction; the other was fixed to the tunnel sidewalls.

Modelling flow pattern transitions for steady upward gas-liquid flow in vertical tubes
TL;DR: In this paper, the authors developed models for predicting flow pattern transitions during steady gas-liquid flow in vertical tubes based on physical mechanisms suggested for each transition, incorporating the effect of fluid properties and pipe size.
