This volume deals with the instability of fluid flows that vary spatially in the streamwise direction. Such flows occur widely in nature and industry, but unlike their parallel flow counterparts have hitherto received little attention. The individual chapters in this book were selected from papers presented at the IUTAM Symposium on Nonlinear Instability of Nonparallel Flows, held in Postdam, New York, in 1993, and provide an extensive insight into the state of research in this area. Particular emphasis is given to analytical techniques and their use to interpret numerical and experimental results.

Weakly nonparallel shear flow instability has also been reviewed by Huerre & Monkewitz () and Herbert () in two different contexts, outlined below. The present review deals with the primary linear instability of essentially nonparallel, 2D and 3D by: 'Sideband instability and modulations of Faraday waves' (with S.P. Decent) Wave Motion, 30, (). 'Nonlinear interaction of standing waves with Faraday excitation', in Nonlinear Instability, Chaos and Turbulence, eds. D.N. Riahi & L. Debnath, pp Computational Mechanics Publ. WIT Press, Southampton UK (). As an example of the second type, a standing wave in a transmission line is a wave in which the distribution of current, voltage, or field strength is formed by the superposition of two waves of the same frequency propagating in opposite directions. The effect is a series of nodes (zero displacement) and anti-nodes (maximum displacement) at fixed points along the transmission line.
