気液二相流流れ加速型腐食における遷移域での液膜厚さの減肉速度への影響

The experiment of Flow Accelerated Corrosion (FAC) under water-steam two-phase flow is performed with changing liquid film thickness in transition region. From the results, the thinning rate is not changed when the liquid film thickness is under about 100 micro meter. However, the thinning rate decreases when the liquid film thickness is over about 100 micro meter. From our prediction model of thinning rate about FAC under water-steam two-phase flow, the thinning rate decreases when the liquid film thickness These results are almost the same trend as our prediction model.
