Particuology 2017年第2期15卷 191-199页

Num.rical techniques have increasingly been used to m.del fluid–particle two-phase flows. Coupling the im.ersed boundary m.thod （IBm. and discrete elem.nt m.thod （DEm. is one prom.sing approach for m.deling particulate flows. In this study, IBm.was coupled with DEm.to im.rove the reliability and accuracy of IBm.for determ.ning the positions of particles during the sedim.ntation process within viscous fluids. The required ratio of the particle diam.ter to the grid size （D/dx） was determ.ned by com.aring the sim.lation results with the analytical solution and experim.ntal data. A dynam.c m.sh refinem.nt m.del was utilised in the IBm.m.del to refine the com.utational fluid dynam.cs grid near the particles. In addition, an optim.m.coupling interval between the IBm.and DEm.m.dels was determ.ned based on the experim.ntal results of a single particle sedim.ntation within silicon oil at a Reynolds num.er of 1.5. The experim.ntal results and the analytical solution were then utilised to validate the IBm.DEm.m.del at Reynolds num.ers of 4.1, 11.6, and 31.9. Finally, the validated m.del was utilised to investigate the sedim.ntation process for m.re than one particle by m.deling the drafting-kissing-tum.ling process and the Boycott phenom.non. Benchm.rk tests showed that the IBm.DEm.technique preserves the advantages of DEm.for tracking a group of particles, while the IBm.provides a reliable and accurate approach for m.deling the particle–fluid interaction.

The therm.l aspects of the flow field are also investigated by assum.ng the surface is a heatedsurface with a constant tem.erature T. Num.rical solutions to the governing m.them.tical m.del are calculatedby the RK45 algorithm. The results based on the num.rical solution against various flow and therm.l controllingparam.ters are presented in term. of line graphs.
