A numerical scheme to simulate three-dimensional two-way fluid–structure interaction (twFSI) problems of flows around a flexible fine structure is developed in this study. The partitioned approach is employed to separately calculate fluid flows and

To describe permeable roughness effects on turbulence statistics, our previously reported PIV (particle image velocimetry) experimental data (Shimizu et al., 2019; Okazaki et al., 2020) of turbulent channel flows over two different permeable roughnes

Direct numerical simulation of turbulent heat transfer over hemispherical roughness is carried out by the double-distribution function lattice Boltzmann method (LBM). The D3Q27 multiple-relaxation-time and D3Q19 regularized single-relaxation-time LBM

Natural convection of a paramagnetic fluid through a partially-heated vertical channel is numerically studied in the presence of a magnetic field from two block magnets placed behind the heated wall. Magnets are aligned with opposite orientations. Th

Imbibition of single droplet onto porous surface can be observed in engineering devices such as the oil mist filter, inkjet printings, etc. This two-phase flow is governed by physical properties of liquid and porous media. When the droplet size is co

Stator coils of automobiles in operation generate heat and are cooled by coolant poured from above. The flow characteristic of the coolant depends on the coil structure, flow condition, solid–fluid interaction, and fluid property, which has not bee

Nonequilibrium molecular dynamics simulations are performed for force-driven argon gas nanochannel flow to investigate the effect of the nanoscopic wall structure on the gas flow characteristics. The monoatomic molecule argon is first used for both t
