    Observations on Rapidly Rotating Turbulence

    Experiments on rapidly rotating turbulence have been reported in recent years in which the Rossby number, Ro, drifts down towards unity as the energy of the turbulence decays (Davidson et al., 2006; Staplehurst e...

    Attenuation technique for measuring sediment displacement levels

    A technique for obtaining accurate, high (spatial) resolution measurements of sediment redeposition levels is described. In certain regimes, the method may also be employed to provide measurements of sediment ...

    A pattern matching technique for measuring sediment displacement levels

    This paper describes a novel technique for obtaining accurate, high (spatial) resolution measurements of sediment redeposition levels. A sequence of different random patterns are projected onto a sediment laye...

    The structure of the head of an inertial gravity current determined by particle-tracking velocimetry

    Digital particle-tracking velocimetry is used to obtain the two-dimensional structure of the head of inertial gravity currents propagating along a no-slip boundary. The early stage of development of lock-relea...

    The drag on a vertically moving grid of bars in a linearly stratified fluid

    We present the results of an investigation of the drag force on a horizontal grid of bars moving vertically through a stratified fluid. A novel approach was used to calculate the drag, based on measurements of...

    A light attenuation technique for void fraction measurement of microbubbles

     A non-intrusive technique to measure the two-dimensional distribution of line averaged void fraction in a two-phase flow is discussed. A CCD camera is used to measure the attenuation of light as it passes thr...

    Whole-field density measurements by ‘synthetic schlieren’

     This paper outlines novel techniques for producing qualitative visualisations of density fluctuations and for obtaining quantitative whole-field density measurements in two-dimensional density-stratified flow...

    Electrical measurement of sediment layer thickness under suspension flows

     This paper reports a new technique to measure the thickness of a layer of deposited sediment as a function of time, independent of the flow conditions or presence of suspended sediment above the layer. Small ...

    Experiments on Turbulence in Stratified Rotating Flows

    The evolution and interaction of approximately two-dimensional flows is of considerable importance to the dynamics of the atmosphere and oceans. The inability to stretch vortex lines in such flows leads to the...
