Interfacial instabilities in exchange flows
Abstract
This paper reports findings from an experimental study of interfacial instabilities in exchange flow through a channel. Kelvin-Helmholtz instabilities were observed at both ends of the channel whileHolmboe instabilities in the middle region. The development ofthe Holmboe instabilities was controlled by the vertical shift of the density interface from the shear center. The amount of the shift changed during the experiments. Measurements ofthe lengths and speeds ofthe Holmboe waves compared weil with the linear-stability theory. Holmboe waves were stabilized when the bulk Richardson number exceeded about 0.8.
