It is required to estimate the fluidelastic instability of tube arrays caused by liquid-gas two-phase flow that the data are measured in the flow condition similar to the practical case as precisely as possible. Heat exchanging tubes in steam-generators in PWR type nuclear power plants are composed by U-shaped curved tubes and shape sphere-type tube bundle. Authors have recently developed a new estimation method, based on a test with two-dimensional U-bend tube array. In this paper, this method is applied to estimate a test which has been done in France, where a three-dimensional U-bend tube bundle is supposed to HCFC-114 two-phase flow. The result shows both tests have good coincidence.
