CFD Study of Behavior of Transition Flow in Distinct Tubes of Miscellaneous Tape Insertions

Application of transition flow can be found in several processes and systems. It has been revealed through findings from various researchers that the values Reynolds numbers at which occurs vary. In current work, investigations were numerically conducted by Fluent on water three assorted plain tubes fitted with miscellaneous tape insertions. They are tube crossed-axes-circle-cut insert (C-C tube), crossed-axes-triangle-cut (C-T crossed-axes-ellipse-cut (C-E tube). The focus work is to explore influence insertion commencement finish respect number flow. (Re) taken into account for 2,150≤Re≤4,650, variation Shear-Stress Transport κ-ω model deals was utilized. results showed starts Re=2,300 finishes Re=4,400 C-T tube, Re=2,780 Re=4,610 C-C but Re=2,550 Re=4,500 C-E tube. Nusselt 19.3% 45.6% higher than 3.6% 28.3% more friction factor 2.15% 4.56% tube; 0.83% 3.33% These indicate case considered this first one commences ends, highest number, last, least number. Interestingly, same phenomenon applies factor. Doi: 10.28991/HIJ-2022-03-02-02 Full Text: PDF
