DESCRIPTION:Caroline Hamilton Smith (University of Sidney)\nAbstract: Cav
 ity flow produces a notable deficit in the performance of ships\, cars\, a
 ircraft and submarines alike\, owing to the presence of complex and unstea
 dy turbulence\, drag\, acoustics\, vibration and structural fatigue. The f
 low is a building block of fluid dynamics\, due to a long list of abundant
  principal flows\; vorticity\, shear layer oscillation\, feedback...\, fro
 m which progressive understanding has fed into contemporary advancement in
  fluid dynamics as a whole. This research documents hot-wire and unsteady 
 surface pressure experiments executed on a range of cavity geometries\, fo
 cusing on how altering upstream geometry and thus boundary layer structure
  impacts internal surface pressures\, and their contribution to fluid resp
 onse. The key finding highlights the drastic impact of measured and simila
 r boundary layer structures on the cavity response\, assessed using  DMD.
  A thin accelerated boundary layer separated dominant eigenvalues within t
 he eigen circle\, with normalised eigenvectors of discrete modal magnitude
 . A thick flat-plate boundary layer instead clumped eigenvalues\, with a l
 ack of discrete mode structures\, shifted in phase and significantly reduc
 ed in magnitude.  Overall\, changes in boundary layer structure\, not onl
 y thickness\, but momentum as a function of upstream pressure gradients\, 
 completely warped the mode shapes. Therefore\, boundary layer structures a
 s a function of external geometry design\, provides constructive ability t
 o control\, and thus predict modes in the spectra\, their dominance and no
 rmalised eigenvector magnitudes with respect to known cavity geometry.\n\n

 pirical and numerical models of the Airbus Fleet Structural Engineering G
 raduate with Airbus Australia Pacific 2020/2021\, primarily in-service rep
 airs\, and upgrade modifications\, including Sat-Com KA-band installation 
 on the C-130J Fleet for RAAF. Commenced a PhD at the University of Sydney 
 end of 2021\, to pursue my love of Aerodynamics\, in the Unsteady Fluid Dy
 namics of Cavity Flow focusing on the Boundary Layer Effect. I have receiv
 ed several Awards to support my research inclusive to the Amelia Earhart F
 ellowship\, Faculty Engineering Scholarship\, and Defence Materials Techno
 logy Support Scholarship. Published in the European Journal of Mechanics B
 /Fluids on the History of Cavity Flow recently\, and at present developing
  a Similarity Cavity Flow Solution article to be published in JFM.
