The subsonic near-wake of an axisymmetric semielliptical afterbody

Turbulence intensities in the near-wake of a semielliptical afterbody

“…A peak in the relative turbulence is found at X/R = 0.2, the rear stagnation point as determined by other methods. 4 Downstream of the rear stagnation point the relative turbulence intensity declines rapidly due to the increase in centerline velocity. The peak in the relative turbulence curve can be used to indicate the rear stagnation point while a look at Fig.…”

“…The information presented in this paper on turbulence intensities, when coupled with the previous work of Yi and Przirembel 3 and Merz et al 4 provides a complete description of the flowfield about a semielliptical afterbody. The results will be useful in developing and evaluating analytical solutions for the flowfield.…”

“…The data presented, along with the previous results of Yi and Przirembel 3 and Merz et al 4 provide a complete description of this flowfield and represent the most extensive set of information available on this flow. They will serve as the basis for the development and evaluation of analytical solutions.…”

“…This study concentrated on the boundary layer, its properties, the separation process, and the criteria for separation. Recently, Merz et al 4 have reported the mean flow characteristics in the near-wake behind the same curved afterbody. To complete the description of this particular flowfield, the turbulence characteristics in the near-wake need to be determined.…”

“…Specifically, the near-wake behind the ellipsoidal afterbody used by Yi and Przirembel 3 and Merz et al 4 was surveyed with a hot-wire anemometer system. Figure 1 shows a schematic of the important flowfield components.…”
