The unsteady evolution of the singularity at separation

Journal of Engineering Mathematics Aims and scope Submit manuscript

Summary

The unsteady boundary layer equations are studied close to a separation point. A perturbation procedure, based on an idea of Kaplun, leads to a nonlinear integro-differential equation for the skin-friction. A uniformly valid small-time analysis of this equation shows how an initial square-root singularity at a separation point is smoothed out by unsteady processes.
