WebThe inadequacies of the recently-proposed “Crighton–Leppington” stability criterion are demonstrated through a number of counter-examples. It is then shown that any impedance lining model not capable of being analysed using the Briggs–Bers criterion is illposed, in WebMay 1, 2009 · The Briggs-Bers criterion [55,56] is used to determine the propagation direction of the modes, and, if an unstable mode is present, whether it is convective or absolute.
In stability theory, the Briggs–Bers criterion is a criterion for determining whether the trivial solution to a linear partial differential equation with constant coefficients is stable, convectively unstable or absolutely unstable. This is often useful in applied mathematics, especially in fluid dynamics, because linear PDEs often govern small perturbations to a system, and we are interested in whether such perturbations grow or decay. The Briggs–Bers criterion is named after R. J. Briggs and A. … WebDec 8, 2024 · However, Brambley [12] showed: firstly, that this criterion is flawed and that the Briggs-Bers criterion has to be used; and, secondly, that the Ingard-Myers boundary condition is mathematically ill-posed since it gives arbitrarily large exponential growth rates for arbitrarily small wavelengths and therefore precludes the Briggs-Bers stability ...
WebThe Briggs-Bers criterion was combined with the spatio-temporal stability analysis to determine the nature of the absolute instability of the jet whether absolutely or convectively unstable. The roles of the density ratio, Froude number, Schmidt number, and the lateral shift between the density and velocity profiles on the absolute instability ...
