A parallel direct-forcing (DF) fictitious domain (FD) method for the simulation of particulate flows is reported in this paper. The parallel computing strategies for the solution of flow fields and particularly the distributed Lagrange multiplier are

We numerically investigate the hydrodynamics of a spherical swimmer carrying a rigid cargo in a Newtonian fluid. This swimmer model, a ‘squirmer’, which is self-propelled by generating tangential surface waves, is simulated by a direct-forcing fi

Correlations for the interfacial terms in the fluid dissipation rate equation and Reynolds stress equations are established for particle-laden flows, based on data from the interfaced-resolved direct numerical simulations of particle sedimentation in

Microorganisms can efficiently navigate in anisotropic complex fluids, but the precise swimming mechanisms remain largely unexplored. Their dynamics is determined by the interplay between multiple effects, including the fluid's orientation order, swi

A drag correlation is established for laminar particle-laden flows, based on data from the interfaced-resolved direct numerical simulations (IR-DNS) of particle sedimentation in a periodic domain at density ratio ranging from 2 to 1000, particle conc

We study the hydrodynamics of a spherical and dumbbell-shaped microswimmer in a tube. Combined with a squirmer model generating tangential surface waves for self-propulsion, a direct-forcing fictitious domain method is employed to simulate the swimmi

Microorganisms may exhibit rich swimming behaviours in anisotropic fluids, such as liquid crystals, which have direction-dependent physical and rheological properties. Here we construct a two-dimensional computation model to study the undulatory swim

Biological swimmers often exhibit rich physics due to the hydrodynamic coupling between the fluid flow and the immersed deforming body. Complexity and nonlinearity of their behaviors have imposed significant challenges in design and analysis of robot

In this paper, we demonstrate that the original Troshko–Hassan model with the correction coefficient being unity should be chosen for an interfacial term in the turbulent kinetic energy equation at the statistically steady state based on the theore

A turbulent channel flow of a binary mixture of finite-size neutrally buoyant ellipsoidal particles is studied by using a parallel direct-forcing fictitious domain method at a friction Reynolds number of 180 and the particle aspect ratios of 1/3 (obl
