A simple model is proposed for the large spiral vortices observed in plane shear layers. An infinite, uniform vortex sheet is perturbed at one point and the resulting flow is studied numerically. A spiral structure appears that grows linearly for large values of time. The growth rates obtained agree with the observed values for the experimental layers within 25%.
