By using the results for a two-dimensional jet flow issuing from a finite width nozzle, an approximate calculation of the reattachment flow having various offsets, inclinations of the reattachment wall and initial turbulence intensities was done and compared with experiments. The calculated results of a reattachment distance agree well with the experimental ones in a wide range of offsets, except very small ones. The approximate calculation reveals that the maximum inclination which maintains the reattachment is independent of both the initial turbulence intensity and the offset. The experimental results show that there exist three distinct regions, that is, a natural reattachment region, a forced reattachment region and a non-reattachment region, according to the inclination. Both the results of the calculation and the experiment reveal that the mean bubble pressure shows the minimum value at a certain inclination.
