WebNov 1, 2024 · The obtained jujube model is imported into the EDEM software, and two jujube simulation models are established by using the particle filling function. The selection of a particle contact model is an important basis for ensuring the accuracy of the simulation results of the simulation analysis model. WebMay 9, 2024 · The DISAMATIC casting process production of sand moulds is simulated with DEM (discrete element method). The main purpose is to simulate the dynamics of the flow of green sand, during the production of the sand mould with DEM. The sand shot is simulated, which is the first stage of the DISAMATIC casting process. mlop in insurance
Some Influences of Saturation and Fluid Flow on Sand Production ...
WebThe model using the computational fluid dynamics coupled with discrete element method (CFD-DEM) can capture micro-scale features of sand transport problems. In this study, coarse-graining methods of a three-dimensional CFD-DEM model are developed to investigate the sand production phenomenon. WebMay 29, 2014 · Sand production in oil wells is often predicted using continuum fluid-coupled models. However, a continuum approach cannot capture important features of the sanding problem, such as erosion and localised failure. This shortcoming of continuum-based analyses can be overcome using the particulate discrete element method (DEM). WebNov 16, 2016 · The results from modeling demonstrated that sand is produced the least in the numerical model using gravel from 3.5 to4.76 mm and sand is produced less in the physical model containing gravel pack ranging from 4.76 to 9 mm and the fluid left more output discharge. mloong baby playpen with mat
