초록정보

A two-dimensional flow generated by the interaction of two curved wall jets over a circular cylinder was investigated experimentally. The location of the interaction and the direction of the merged jet were found to depend primarily on the ratio of initial momentum fluxes. Since the merged jets from the two curved wall jets having various momentum flux ratios did not differ from one another in character, the investigation of the flow properties for the case of the interaction of two symmetric curved wall jets was intensively carried out. The overall flow field was divided into the curved wall jet region, the interaction region and the merged jet region: the results of measurements were discussed to characterize these three distinct regions. For the curved wall jet region, the Reynolds stress distribution, triple moment profiles and turbulent structural parameters were presented and the effects of curvature and adverse pressure gradient were discussed. The Reynolds stress distributions in the interaction region were analyzed to illuminate the counter-gradient shear stress and negative production of the turbulent kinetic energy. Measured data in the merged jet region were often compared with those of conventional plane jets and the development of the merged jet was discussed in that respect. The spreading rate of the present merged jet was found to be much larger than that of plane jet. To account for the larger spreading rate, the intermittent properties of the flow was investigated. The Reynolds stress budgets in the interaction region and similar region were carefully evaluated based on measured data.
