A technique is described for deducing a class of unsteady asymptotic s
olutions of the two-dimensional Euler equations. In contrast to previo
usly known analytical results, the vorticity function [omega(x, y, t)]
for these solutions has a complicated dependence on the spatial coord
inates (x, y) and time (t). The results obtained are in implicit form
and are valid in those regions of space and time where t omega --> 0() or t omega --> +infinity. These asymptotic solutions may be split in
to an unsteady, two-dimensional and irrotational basic flow and a dist
urbance that is strongly nonlinear at appropriate locations within the
domain of validity. The generality and complexity of these solutions
make them theoretically interesting and possibly useful in application
s.
