Description

Characteristics of thermal-hydraulic phenomena in the steam injector were examined. Two types of test section of a straight type and an injector type were used. Large waves were observed on the water jet. The waves showed the tendency to grow as proceeded downstream. The Kelvin-Helmholtz instability predicted the water jet disruption conservatively. The conservatism became more prominent in the injector type. It was confirmed that the present design of the steam injector could pump up five times higher. (author)
