AYALA-HERNANDEZ, A. e HIJAR, H.. Flow between two coaxial cylinders simulated by multiparticle collision dynamics. Rev. mex. fis. [online]. 2016, vol.62, n.6, pp.500-509. ISSN 0035-001X.
We carry out simulations of multiparticle collision dynamics fluids confined in the region between two coaxial cylinders. In order to confine these fluids in this geometry, we apply the method based on explicit fluid-solid forces introduced in a recent publication . We consider two independent situations in which, first, flow is produced by a uniform pressure gradient that points along the axial direction and, second, azimuthal flow is induced by a centrifugal force field. We generalize the methodology introduced in Ref. and show, through a large number of numerical experiments, that the correct flow expected from hydrodynamics can be obtained in the two previous cases, with conditions at the fluid-solid interaction regions that can be adjusted from partial-slip to no-slip boundary conditions.
