Emphasis is placed on describing the Lagrangian dynamics of thermally-strati ed flows at Rayleigh numbers Ra = 2.8*10^9 and 1.1*10^10 for aspect ratios of 1.2, and 2. For this purpose, three-dimensional particle tracking velocimetry (3D-PTV) was used to characterize the three-dimensional Lagrangian paths of tracer particles in RB. The work also provides a general methodology for data pre-processing along with flow data post-processing. Lagrangian statistics including velocity and acceleration possibility density functions as well as pair dispersion are explored in detail. Inspection of the dynamics of buoyant particles, namely bubbles, are also discussed.","Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2021-05-01","The student, Shikun Shen, accepted the attached license on 2019-04-25 at 11:27.","The student, Shikun Shen, submitted this Thesis for approval on 2019-04-25 at 11:36.","This Thesis was approved for publication on 2019-04-25 at 17:05.","DSpace SAF Submission Ingestion Package generated from Vireo submission #13910 on 2019-08-22 at 15:08:37","Made available in DSpace on 2019-08-23T20:36:12Z (GMT).
