Experi imental and Numerical N Stud dy of Swirling g Flow in Scaveenging Processs for 2-Stroke Marin ne Diesel Engin nes Figure F 4.19: Normalized N Reyno olds St tress Component t @ z3 L3=4D Chapter 4 At z5 in figure 4.20 0, the oval shhape region, wwith large deeviations in v , elongat tes and tilts further f in annticlockwise ddirection. Simmilar to u , thhe deviatio on in v com mponent in thhe vortex coree region, reduuces quickly at higher Reynolds nu umber ReA coompared to llower at ReBB (Figure 4.200).

Experi imental and Numerical N Stud dy of Swirling g Flow in Scaveenging Processs for 2-Stroke Marin ne Diesel Engin nes Figure 4.20: No ormalized Reyno olds St tress Component @ z5 L3=4D The an nalysis of Rey ynolds stress components uu and v v v (Cartesiaan coordin nates) indicate es that vv and vv r r aree larger near the wall and in the vor rtex core regio ons at z1. Thee radial distannce, from thee vortex centeer, where v rv r increase es towards the vortex center, , is larger thann the vv annd follows the same for both Reynoldds numbers (FFigures 4.15 annd 4.18). As thhe swirl de ecays downstre eam, the magnnitude of radiaal and tangenttial fluctuationns decrease e but their spa atial distributiion increase too larger radial distances of thhe cylinder cross-section n. However, at all position vv is more spatiallly r r Chapter 4 71 Swirling Flow in a Pipe
