Modelling sediment resuspension in industrial tanks using SPH

Composite modelling of subaerial landslide–tsunamis in different water body geometries and novel insight into slide and wave kinematics

“…The first attempt to apply the method to free-surface flows was undertaken by Monaghan (1994), where it was understood that, in contrast to most other numerical methods, SPH requires no explicit treatment of the free water surface (Dalrymple and Rogers, 2006). Furthermore, SPH can inherently deal with bi-phasic problems with a low density ratio (Fourtakas et al, 2013).…”

Tsunami wave and structure interaction: an investigation with smoothed-particle hydrodynamics

“…The method has found widespread application in engineering for industries involving hydrodynamics, impact fracture, mould filling and high temperature (Muhammad et al, 2013). Within the field of hydrodynamics, the SPH method has been used at the University of Manchester to simulate a range of potentially violent phenomena including wave breaking, dam breaks, greenwater overtopping (Dalrymple and Rogers, 2006), waves impacting moving caisson breakwaters , solving the shallow water equations for flooding and inundation (Vacondio et al, 2011(Vacondio et al, , 2012(Vacondio et al, , 2013, pulsatile flow in a human left ventricle (Shahriari et al, 2012), wave interaction with floating wave energy devices (Omidvar et al, 2012(Omidvar et al, , 2013, water slam problems (Skillen et al, 2013), sediment suspension in industrial tanks (Fourtakas et al, 2013), laser processing (Muhammad et al, 2013), and wave interaction with partially submerged rubble mound breakwaters (Altomare et al, 2014).…”

SPH Modelling of Hydraulic Jump Oscillations at an Abrupt Drop

“…A schematic figure of the problem setup can be seen in Figure 4. A thorough sensitivity analysis was already performed by the authors in the application of the same SPH numerical method to hydraulic jumps and breaking wave flows ( [30,47]): according to this analysis, the SPH simulations of the cases here studied were performed by adopting a velocity smoothing coefficient in the XSPH scheme φv = 0.01. The ratio of the smoothing length to the initial particle spacing Σ was maintained to a constant value of η/Σ = 1.5 [74] for all the simulations.…”

“…The peculiar features of the SPH method used to obtain the present results were described in detail in ( [30,47]): simulations are performed through a Weakly Compressible SPH (WCSPH) approach, in which an artificial compressibility is introduced to solve explicitly in time the equations of motion of an incompressible fluid. As suggested by [59], the reduced value of the speed of sound should result in a numerical Mach number everywhere lower than 0.1 in order to bound the error associated with the adoption of a compressible formulation for the incompressible free-surface water flow to 1%: here, the adopted value of 30 ms −1 guarantees a numerical Mach number everywhere lower than 0.07.…”

“…Smoothed Particle Hydrodynamics (SPH) is actually effective in solving fluid-dynamic problems with highly non-linear deformation such as wave breaking and impact ( [23][24][25][26][27][28]); multi-phase flows for coastal and other hydraulic applications with air-water mixtures and sediment scouring ( [29][30][31][32][33][34][35]); long waves, e.g., floods, tsunamis and landslide submersions ( [36,37]); flow around ships and ditching ( [38][39][40]); and oscillating jets inducing breaking waves [41].…”
