|Issue Date:||Nov-1993||Citation:||Khoo, B.C.,Yeo, K.S.,Yao, S.E. (1993-11). Effusing core at the center of A potential vortex. Experimental Thermal and Fluid Science 7 (4) : 307-318. ScholarBank@NUS Repository.||Abstract:||Experiments were carried out to measure the base pressure distribution of a flow field induced by a potential vortex with its axis normal to a stationary disk. The center base pressure coefficient of the vortex, C0(0), was found to be proportional to Reynolds number from Re = 2.0 × 103 to Re > 2.5 × 104, where Re is based on the disk radius and azimuthal velocity at the disk edge. This behavior of C0(0) is at variance with the experimental results of Phillips (Phys. Fluids, 27, 2215, 1984) and Khoo (M. Eng. Thesis, Natl. Univ. Singapore, 1984), which showed vastly different trends depending on Re. Plausible reasons are suggested for the apparent discrepancies observed. Finally, the extent of the effusing core at the center, r1 (taken to be the radial position where departure from the outer potential flow took place), was found to be proportional to Re -1 2 for all Re values considered. © 1993.||Source Title:||Experimental Thermal and Fluid Science||URI:||http://scholarbank.nus.edu.sg/handle/10635/92694||ISSN:||08941777|
