Summary: The study simplified the Lattice Boltzmann Method algorithm by assuming constant numerical viscosity and conducted simulations to test it. The results showed that the new method is simpler and less error-prone in implementation, requiring less working memory in low Reynolds number flows but less efficient in multiphase flows. Therefore, further extension and the moments-only formulation were proposed to address this issue.

Summary: The lattice Boltzmann Method was used to simulate fluid flow in a Lid-driven cavity with different wavelengths corrugated walls. The results showed that the position, number and size of vortices depend on the number of corrugations and value of Reynolds number used. As the Reynolds number increases, the size of secondary vortices also increases, and the kinetic energy distribution shows maximum energy near the top wall, decreasing inside the cavity.

Summary: A general computational tool for deriving equivalent partial differential equations (EPDEs) in lattice Boltzmann method (LBM) with different collision operators is proposed. The tool can recover various dimensions of advection-diffusion equations (ADEs) and Navier-Stokes equations (NSEs). It starts with the lattice Boltzmann equation and uses spatio-temporal Taylor expansion to obtain a system of partial differential equations. An algorithm is proposed to eliminate higher order moments and recover the desired equations. The tool, named LBMAT, is implemented as open-source software for symbolic algebraic computations.

Summary: This paper validates the application of lattice Boltzmann method (LBM) to a high-subsonic high-pressure compressor stage, showing that the finest grid can accurately predict the mean flow across the machine and the influence of rotor tip gap size. The study demonstrates the relevance of using this high-fidelity method in compressor configurations by highlighting vortical structures and their evolution with operating points. Spectral analyses suggest that LBM provides a proper prediction of tonal and broadband contents in the flow.

Summary: Hydroacoustic analyses using direct methods are challenging in the field of computational physics. Hybrid methods have been used as an alternative approach, but they have limitations in analyzing nonlinear turbulent noise. The lattice Boltzmann method (LBM) provides a solution to address these limitations, and a new collision operator, the DM-TS operator, is introduced to solve stability problems. The results demonstrate that the proposed method can be used to simultaneously obtain dynamic and acoustic pressures.

Summary: This article numerically studies the magneto hydrodynamic (MHD) mixed convection of titanium oxide/water nanofluids (NFs) in a T-shaped two-dimensional cavity. The results show that an increase in the slip parameter can reduce the entropy generation and slightly decrease the Nusselt number, while both of them increase when the Richardson number reaches a certain range.

Summary: This paper investigates the flow field and heat transfer in a microchannel with surface hydrophobicity and considering its thickness. A partial magnetic field is applied to the top thermal-insulated wall in the microchannel. The results show that viscous dissipation and heat transfer decrease with increasing slip coefficient at Ha = 0. Additionally, raising the Hartmann number increases the friction coefficient. The Nusselt number reaches its highest value at Ha = 20 for all cases, but then decreases as Ha increases.

Summary: This study investigates the influence of magnetic field on pulsatile blood flow and heat transfer in an artery with aneurysm using the mesoscopic lattice Boltzmann method. The results show that the application of a magnetic field enhances heat transfer in the inlet zone of the aneurysm, reduces recirculation zones, and increases wall shear stress, thereby preventing the progression of vascular diseases and rupture in the aneurysm region.

Summary: This study examines the impact of rotor speed on the aerial spraying effect of UAVs. By using numerical simulation and experimental verification, it is found that increasing rotor speed leads to higher wind speed and vorticity in the downward airflow, with the maximum values mainly concentrated below the rotor. However, these maximum values decrease over time. The results provide insights for optimizing spraying operations and improving the effectiveness of plant protection UAVs.

Summary: This study applies the innovative technology of a square wave pulsating flow combined with a spherical corrugated wall structure in a helical tube to enhance heat transfer. The unsteady flow structure and heat transfer characteristics are numerically investigated, and the effects of pulsating parameters on heat transfer enhancement performance are explored. The results show that the disturbance induced by the pulsating flow improves the local flow field and enhances the secondary flow and turbulent kinetic energy. The Nusselt number is significantly greater than that in steady flow, and the optimum dimensionless pulsation frequency and amplitude are determined.
