Autor: Akitaka Hidaka, Katsumasa Miyazaki, Kotoji Ando, Masakazu Hisatsune, Yoshio Urabe, Sota Watanabe, Koji Takahashi

Publikováno v: Nuclear Engineering and Design. 239:2719-2727

Low cycle fatigue tests were conducted using 100A elbow specimens made of STPT410 carbon steel with local wall thinning. Local wall thinning by erosion/corrosion was simulated by machined pipe wall thinning. The local wall thinning areas were located

Failure behavior of carbon steel pipe with local wall thinning near orifice

Autor: Koji Takahashi, Kotoji Ando, Masakazu Hisatsune, Kunio Hasegawa

Publikováno v: Nuclear Engineering and Design. 237:335-341

Monotonic four-point bending tests were conducted using pipe specimens having an orifice undergoing local wall thinning. The effects of local wall thinning on the fracture behaviors of pipe were investigated. Local wall thinning was machined on the i

Prediction of vortex penetration depth at thermal stratification by cavity flow in a branch pipe with closed end (effect of heat radiation condition on temperature fluctuations)

Autor: Shoichi Moriya, Tadashi Mizuno, Kenji Ogura, Haruki Madarame, Masakazu Hisatsune, Kouichi Tanimoto, Tsutomu Kawamura, Kouji Shiina, Toshihiko Fukuda, Masaya Ohtsuka, Yasuhiko Minami

Publikováno v: Heat Transfer—Asian Research. 36:38-55

In a branch pipe with one closed end, the cavity flow penetrates into the branch pipe from the main loop and a thermal boundary layer occurs because the cavity flow is a hot fluid, but heat removal causes a colder fluid in the branch pipe. This therm
