    Some aspects of internal wave motions (1976)

    Notes: Summary Internal waves are considered on the hypotheses of small disturbances and the Boussinesq approximation. Consideration is given to the lowest internal mode propagating along athin thermocline, and an approximate calculation is made of the dispersion relation, including an explicit representation of the dominant correction for thermocline thickness. Then, the Stokes drift velocity is calculated (a) approximately for this mode in the thin-thermocline model, and (b) numerically for the first two internal modes associated with a single thick thermocline. Finally, a calculation is made of the mass transport velocity field induced by the interaction between pairs of waves (surface or internal), having thesame frequency but arbitrary directions of propagation.

    Damping characteristics of gravity waves obliquely incident on a monomolecular film: Part II (1985)

    Notes: Abstract Calculations of viscous damping chracteristics of gravity waves, propagating obliquely across finite monomolecular films, are represented graphically to demonstrate the influence of angle of incidence, film edges, and surfactant properties. It is found that regions of negative damping may occur, particularly towards the rear of extensible slicks. For wide slicks, both the amplitude and the domain of significant edge effects on the local damping coefficient decrease with angle of incidence. Multiple-slick systems can damp waves more effectively—with appropriate choice of surface-active material—than an equivalent single slick.

    On progressive internal waves in non-uniform depths (1970)
    Springer
    Pure and applied geophysics 83 (1970), S. 87-97 
    Details
    ISSN: 1420-9136
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences , Physics
    Notes: Summary An expansion technique is used to investigate effects of finite amplitude on three-dimensional progressive internal waves in continuously stratified fluid of variable depth. The results are illustrated for the case of uniform density gradients. Reflection is neglected in the perturbation scheme. In two dimensions, damping of long progressive waves is considered through energy dissipation in the bottom boundary layer.

    Double boundary layers in standing surface waves (1976)
    Springer
    Pure and applied geophysics 114 (1976), S. 629-637

    Notes: Summary The double boundary-layer theory ofStuart (1963, 1966) andRiley (1965, 1967) is employed to investigate the mass transport velocity due to two-dimensional standing waves in a homogeneous fluid. The double boundary-layer structure occurs only at the bottom, and the existence of jet-like motions is predicted, due to the nature of the mean flows in the bottom boundary layers. A vector equation governing mean motions in the secondary layer is derived for threedimensional wave motions.

    Notes: Abstract Viscous damping characteristics of long-crested gravity waves, propagating obliquely through a long monomolecular film of finite width, are considered for physical situations in which the wind is absent. The methods employed in the investigation are based on boundary-layer techniques, and formulae are derived for the local spatially-dependent decay coefficient and amplitude-function due to propagation of deep-water waves across extensible films. In II, such formulae are illustrated graphically to demonstrate the influence of angle of incidence, film edges, and surfactant properties, and some reference is made in relation to practically realisable values of the surface elasticity χ.

    Numerical comparisons of the damping of internal gravity waves in stratified fluids (1970)
    Springer
    Pure and applied geophysics 79 (1970), S. 53-65 
    Details
    ISSN: 1420-9136
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences , Physics
    Notes: Summary Comparisons are made of the attenuation of progressive internal waves in stratified fluids consisting of (a) a representation of a single thermocline, (b) a weak exponential density distribution and (c) a two-layer system. Effects of the earth's rotation are neglected, as also are heat and salt diffusion. Significant differences are found in the decay characteristics of the three density structures. Internal waves are most strongly damped in the layered system (c) whilst the calculated attenuation rates are least for the thermoclinic structure (a). All the internal modes investigated are, however, shown to be more strongly damped than the associated surface wave.

    The viscous damping of internal waves on the rotating earth (1968)

    Notes: Summary A formula is derived for the spatial attenuation of the two possible modes of oscilation of a two-layer, rotating system. If the long-wave approximation is made, it is found with reference to the internal mode that this formula disagrees with an earlier result obtained byRattray [8]2).

    Description / Table of Contents: Zusammenfassung Das fluktuierende Geschwindigkeitsfeld eines monomolekularen Films (Slik) wird mittels der Grenzschichttheorie für den Fall untersucht, daß Schwerewellen sich auf der Grenzfläche zwischen Wasser und Luft ausbreiten. Es wird dabei angenommen, daß das oberflächenaktive Material viskoselastische Eigenschaften aufweist und unlöslich ist. Es werden graphische Ergebnisse wiedergegeben, die die Geschwindigkeit a) im Zentrum des elastischen Sliks und b) für nicht dehnbare Sliks willkürlicher Weite veranschaulichen. Für letzteren Fall werden Ringe von oberflächenbildenden Elementen berechnet und schematisch dargestellt.
    Notes: Summary The fluctuating velocity field of monomolecular slicks is investigated, by means of boundary-layer theory, whengravity waves propagate on the air-water interface. It is assumed that the surface-active material has visco-elastic properties and is insoluble. Graphical results are given, which illustrate the velocity (a) at the centre ofelastic slicks and (b) for inextensible slicks, of arbitrary width. In the latter case, the orbits of the surfactant elements are calculated, and shown diagrammatically.

    Description / Table of Contents: Summary The three-dimensional mass transport velocity field is investigated with reference to the interaction of two longcrested wave trains of equal period propagating in arbitrary directions. When short-crested waves are formed, the time-averaged paths of the fluid particles lie on infinite cylinders with axes parallel to the direction of propagation. There is found to be a non-zero net mass flow along lanes of width one-quarter of a wavelength in the transverse direction.
    Notes: Sommario Si esamina il campo di velocità tridimensionale nel trasporto di massa con riferimento alla interazione di due treni d'onde dalle creste lunghe di uguale periodo che si propagano in direzione arbitraria. Quando si formano onde dalle creste corte le traiettorie medie rispetto al tempo delle particelle fluide giacciono su cilindri infiniti con assi paralleli alla direzione di propagazione. Si constata che esiste un flusso di massa di reticoli non zero secondo canali di larghezza un quarto della lunghezza d'onda nella direzione trasversale.

    A double boundary-layer model of mass transport in progressive interfacial waves (1978)
    Springer
    Journal of engineering mathematics 12 (1978), S. 289-301

    Notes: Summary A double boundary-layer model is used to facilitate calculation of the mass transport velocity due to two-dimensional gravity waves propagating along the interface between two semi-infinite homogeneous fluids. The magnitude of this velocity in the interfacial boundary layers is found to increase with distance from the wave generating region and, in the far field, dominates the Stokes drift velocity. In the case of air above water, the mass transport in the water is such that the presence of the air may be neglected for waves of legnth much less than a metre, but is dominated by the effect of the air when the wavelength greatly exceeds a metre.
