Three-dimensional long-wave instability of unidirectional spatially periodic viscous flows
Published online by Cambridge University Press: 26 April 2006
Abstract
The long-wave instability of unidirectional spatially periodic flows is investigated by means of asymptotic expansions. It is shown that the wavevector of the most dangerous disturbances is generally inclined to the direction of the basic stream. A new type of long-wave oscillatory instability is discovered, and a comparison with results of previous investigations is performed.
