Dimensional Wave

In this paper we examine the stability of a two-dimensional wake profile of the form u(y) = U∞(1 – r e-sy2) with respect to a pulsed disturbance at a point in the fluid. The disturbed flow forms an expanding wave packet which is convected downstream. Far downstream, where asymptotic expansions are valid, the motion at any point in the wave packet is described by a particular three-dimensional wave having complex wave-numbers. In the special case of very unstable flows, where viscosity does not have a significant influence, it is possible to evaluate the three-dimensional eigenvalues in terms of two-dimensional ones using the inviscid form of Squire's transformation. In this way each point in the physical plane can be linked to a particular two-dimensional wave growing in both space and time by simple algebraic expressions which are independent of the mean flow velocity profile. Computed eigenvalues for the wake profile are used in these relations to find the behaviour of the wave packet in the physical plane.

Two Stages

The oxidation of gaseous glyoxal has been studied at temperatures between 290 and 370 °C both manometrically and by detailed product analysis. The reaction has been shown to occur in two stages; in the first, glyoxal reacts to give mainly carbon monoxide and glyoxalic acid and in the second, glyoxalic acid is subject to further oxidation to oxalic acid, hydrogen peroxide, carbon dioxide and water. Of the two previous investigations of the reaction, that of Steacie, Hatcher & Horwood (1935 a ) has been shown to have been concerned with the first stage and in the other (Newitt, Baxt & Kelkar 1939), carried out at ignition temperatures, the reaction proceeded through both stages. The oxidation is accompanied by an oxygen induced decomposition and a mechanism similar to that proposed by one of us (Axford & Norrish 1948) for the oxidation of formaldehyde, involving OH, CHO and HO 2 radicals has been developed and shown to account satisfactorily for the observed facts.
