Abstract
In this paper the solution to the three-dimensional and unsteady
interacting boundary-layer equations for a vortex approaching a cylinder
is calculated. The flow is three-dimensional and unsteady.
The purpose of this paper is to enhance the understanding
of the structure in three-dimensional unsteady boundary-layer separation
commonly
observed in a high-Reynolds-number flow. The short length scales associated
with
the boundary-layer eruption process are resolved through an efficient and
effective
moving adaptive grid procedure. The results of this work suggest that like
its
two-dimensional counterpart, the three-dimensional unsteady
interacting boundary layer
also terminates in a singularity at a finite time. Furthermore,
the numerical calculations
confirm the theoretical analysis of the singular structure in two dimensions
for the
interacting boundary layer due to Smith (1988).
