“…required by the Particle Image Velocimetry Method (PIV), is, in general, avoided since it is possible to modify the two-phase flow topology, especially in the vapour region (Mueller et al 2013). Hence, PTV, according to which bubbles (or vaporous structures) are tracked over successive time frames constitutes a valid and preferred approach (Kitagawa et al 2005;Seol et al 2007;Sathe et al 2010;Pang & Wei 2013) for the determination of the local velocity field and turbulence intensity (Kitagawa et al 2005;Bröder & Sommerfeld 2003).…”

High-speed X-ray phase-contrast imaging of the cavitating flow developing within an axisymmetric throttle orifice has been conducted using high-flux synchrotron radiation. A white X-ray beam with energy of 6 keV was utilized to visualize the highly turbulent flow at 67 890 frames per second with an exposure time of 347 ns. The working medium employed was commercial diesel fuel at flow conditions characterized by Reynolds and cavitation numbers in the range of 18 000–35 500 and 1.6–7.7, respectively. Appropriate post-processing of the obtained side-view radiographs enabled the detailed illustration of the interface topology of the arising vortical cavity. In addition, the visualization temporal and spatial resolution allowed the correlation of the prevailing flow conditions to the periodicity of cavitation onset and collapse, to the magnitude of the underlying vortical motion, as well as to the local turbulence intensity.

“…The velocity and pressure data from LES were analyzed using the mathematical techniques such as multiresolution analysis [85], wavelet transforms (discrete and continuous), proper orthogonal decomposition (POD), and hybrid POD-wavelet techniques (Tabib and Joshi [86], Tabib et al [87], Sathe et al [88], and Mathpati et al [89]). These techniques give the size, shape penetration depth, and energy content of all the flow structure in the system.…”

Large eddy simulations (LES) of dispersed gas-liquid flows for the prediction of flow patterns and its applications have been reviewed. The published literature in the last ten years has been analysed on a coherent basis, and the present status has been brought out for the LES Euler-Euler and Euler-Lagrange approaches. Finally, recommendations for the use of LES in dispersed gas liquid flows have been made.
