| Summary: | A theoretical investigation into the vortex-speed selection within the rotating-disk boundary layer is conducted. Two methods are used which are different to previous investigations in the literature and enable analysis of a particular vortex speed with respect to the rotating surface. Using these methods (together with arguments based on critical Reynolds numbers, unstable parameter ranges and linear growth rates) it is hypothesised that crossflow modes travelling at around 75% of the disk surface are likely to be selected in applications where smooth, clean disks are used, for example in Chemical Vapour Deposition (CVD) reactors. |
