Diffusion of Three-Dimensional Slot Jets With Deep and Shallow Submergence
… discharging the heated water with high initial velocity it behaves like a non-buoyant jet. The velocity discontinuity between the jet and the receiving water gives rise to strong shearing action generating turbulence, which diffuses the heated water into the colder water keeping the temperature …

Teleseismic imaging of the Slave craton and implications for the assembly of cratonic lithosphere
… the depth dependence of Rayleigh wave phase velocity, shear wave velocity, and azimuthal anisotropy of the Slave cratonic lithosphere. The tomographic images reveal high shear wave velocities associated with a particularly depleted, cold, and unperturbed Archean cratonic lithosphere. …

Seismic discontinuities and order estimation using wavelets : a receiver function approach
… techniques to estimate the order and scale of velocity discontinuties in the mantle transition zone through waveform analysis of Pds converted waves. The converted phases are isolated through a single station/multiple event receiver function technique which uses a wavelet deconvolution and …

Computational studies of viscoelastic multiphase flows
… fluids, simulations show that the rise velocity oscillates before reaching a steady value. The shape of the bubble, the magnitude of velocity overshoot and the amount of damping depend mainly on c and the bubble radius. Simulations show that there is a critical bubble volume range in …

Imaging the D" Structure using Waveform Modelling
… The top of D'' region characterises a velocity discontinuity - the D'' discontinuity, which likely originates from the phase transition from bridgmanite (Bm) to post-perovskite (pPv) at the pressure-temperature conditions of the lowermost mantle. This discontinuity has been widely …
