This thesis provides evidence that the wake is fully turbulent at Reynolds number 400. We develop a direct numerical simulation at this Reynolds number, compare it with exper-imental cases at Reynolds numbers 12500 and 19700 and contrast with another simulation at 150 to show the differences from laminar wakes. We find strong agreement between the Reynolds number 400 wake and wakes at much higher Reynolds numbers for all statistical quantities examined. We also show the far wake evolution, energy spectra, and stochastic behaviour of gradient quantities in the Reynolds number 400 wake are typical of turbulent wakes.","abstract_html":"The wake of a thin flat plate normal to uniform flow exhibits unique behaviour, with much research suggesting it undergoes a fundamentally different Reynolds number-dependent tran-sition process to turbulence than wakes behind canonical geometries.
