Cargnelutti, M.F. (author), Belfroid, S.P.C. (author), Schiferli, W. (author), TNO Industrie en Techniek (author)Two-phase flow occurs in many situations in industry. Under certain circumstances, it can be a source of flow-induced vibrations. The forces generated can be sufficiently large to affect the performance or efficiency of an industrial device. In the worst-case scenario, the mechanical forces that arise may endanger structural integrity. Thus, it...conference paper 2010
