概要
For seismic safety of piping system with local thinning surface by liquid droplet impingement erosion (LDI), hybrid tests?? were conducted to the piping with locally-thinned elbow. I n this presentation, determination method of the thinning shape on the elbow is developed.To determine the thinning shape by LDI, droplet behavior at the elbow is calculated in vario us flow and piping size conditions, and collision point and velocity for each droplet is evaluated. Then, the relationship between collision conditions and thinning rate is assumed f rom existing knowledge and thinning shape is determined. The evaluated thinning shape is compared with actual LDI case for the validation of the method, and the method is confirmed.
