概要
The pipe thinning phenomenon which is due to flow accelerated corrosion (FAC) is one of the major causes of unex pected troubles at current nuclear power plants. In order to prevent these troubles in the future, it is highly important to understand and analyze FAC mechanism. So, we calculated three dimensional flow to evaluate a turbul ence energy and a mass transfer coefficient at pipe surface which is one of the key parameters of corrosion model
