Solid quantization for non-point particles [PDF]
Canadian Journal of Physics, 2012 In quantum field theory, elemental particles are assumed to be point particles. As a result, the loop integrals are divergent in many cases. Regularization and renormalization are necessary in order to get the physical finite results from the infinite ...

Eulerian–Eulerian RSTM-PDF Modeling of Turbulent Particulate Flow
Mathematics, 2023 A novel 3D computational model was developed for the turbulent particulate two-phase flow simulation in the rectangular channel. The model is based on the Eulerian approach applied to 3D Reynolds-averaged Navier–Stokes modeling and statistical ...

Impact characteristics and erosion mechanism of solid particles in a centrifugal pump
Frontiers in Energy Research, 2023 To study the impact and erosion mechanism of solid particles in centrifugal pumps, the standard k–ε turbulence model and SIMPLE algorithm are adopted in this paper. Based on the discrete phase model (DPM) of the Lagrange method and McLaury erosion model,

Patterning Behavior of Hybrid Buoyancy-Marangoni Convection in Inclined Layers Heated from Below
Fluids, 2022 Alongside classical effects driven by gravity or surface tension in non-isothermal fluids, the present experimental study concentrates on other exotic (poorly known) modes of convection, which are enabled in a fluid layer delimited from below by a hot ...

Prediction of erosion rate in gas-solid flow using computational fluid dynamics (CFD): focus on geometrical parameters [PDF]
Iranian Journal of Chemical Engineering, 2023 In this study, the fluid flow together with solid particles has been studied using Computational Fluid Dynamics (CFD). The gas-solid flow (air and sand particles with the size of 150 µm) inside a 76.2 mm diameter pipe with various bend angles including ...
