“…To estimate ᐉ t , the method of least-squares may be systematically applied as performed recently by Vatistas 38 in a problem involving a rotating vortex. Based on nearly 900 experimental points acquired at different vortex Reynolds numbers by Rom 39 and Anderson et al 40 one finds, to good approximation, ᐉ t Ӎ 152 ͑see Maicke and Majdalani 41 ͒. This empirical correction enables us to extend the range of validity for Eq.…”

“…5 the simulated vortex chamber assembly and computational grid are shown. Note that a 22.5°periodic boundary condition is used to exploit the pres- The test measurements are acquired through PIV and an experimental apparatus that is elaborately described by Rom 39 and Anderson et al 40 In representing the vortex chamber wall, a 360°quartz cylinder is securely clamped between two adjustable faceplates. Seeding is then provided by means of a Corona smoke generator that produces average particle sizes of 0.2 m. To capture the motion of swirling particles, a laser beam is used to illuminate a planar sheet at right angles to the z-axis.…”

“…In the case of multiple mantles, our theoretical predictions have been employed by [123] to authenticate the multidirectional swirl patterns captured both in their PIV experiments and numerical simulations. In some cases, Anderson and co-workers reported, almost paradoxically, better agreement between the present theory and their measurements than could be achieved with numerical simulations alone.…”

“…Other relevant solutions include those describing the presence of multiple mantles, 12 viscous core corrections, 11 tangential boundary layers, 22 and both radial and axial sidewall boundary layers. 8 Numerical and experimental investigations of the vortex chamber have also been performed by Anderson et al, 2 Rom, Anderson and Chiaverini, 23 Murray et al, 24 Sauer et al 25 (using LOX/RP-1), Chiaverini et al 4 (using O2/H2), Fang, Majdalani and Chiaverini, 26,27 (using both cold and reactive flow conditions), and others. Due to the striking similarity between a bidirectional vortex and a cyclonic flowfield, other pertinent models include those by Fontein and Dijksman, 28 Smith, 29, 30 Bloor and Ingham, 31,32 and Kelsall.…”

“…IGHLY rotating flows are among the most feature-rich motions that are encountered in the analysis of swirling fluid formations. From the devastating power of tornadoes and hurricanes that occur in nature 1 to the vortex-2 American Institute of Aeronautics and Astronautics fired thrust chambers [2][3][4] that are developed for space exploration, highly swirling flows exhibit some of the most intriguing and predictively daunting characteristics. In this vein, a substantial amount of research has been invested in studying both confined [5][6][7][8][9][10][11][12] and unconfined swirling configurations.…”
