    Abstract

    Instability of boundary layers over a concave wall and a rotating disk which were thought to be essentially different in instability sources, are compared in order to investigate whether or not a single crossflow parameter can be defined. Using a newly defined crossflow parameter, prediction was attempted on a yawed cylinder boundary layer transition. By comparing the calculation with the experiment, it was found that this parameter can document fairly well the onset of crossflow instability.
