Summary: This work focuses on the discrete effects of curved boundary conditions in the lattice Boltzmann method for convection-diffusion equations. A new strategy is proposed to eliminate numerical slip, showing its effectiveness through mathematical derivations and simulations. The results support the proposed strategy's ability to achieve uniform relaxation times and remove numerical slip in cases of curved boundaries.

Summary: This study investigated the flowing behaviours of circulating tumour cells (CTCs) under blood flow, focusing on factors such as vessel curvature, cell deformability, and the presence of red blood cells (RBCs). The results showed that at low flow rates, viscous force and vessel curvature played important roles in the formation of bond numbers, while shear force on softer tumour cells stimulated the formation of more ligand-receptor bonds. Additionally, the presence of RBC suspensions increased drag force and promoted disassociation of CTCs from vessel walls.

Summary: In the entropic lattice Boltzmann approach, the parameter alpha governs the stability properties and viscosity of a flow. This study addresses the problem of evaluating alpha to secure the fulfillment of the discrete H-theorem with an average value close to alpha = 2. The proposed method approximates the H-function by a quadratic function and derives an analytical expression for alpha based on the entropy balance requirement. Simulation results validate the formula by demonstrating very small excessive dissipation.

Summary: In this paper, an accurate interface-capturing lattice Boltzmann method is proposed based on the modified Allen-Cahn equation for modeling an immiscible multiphase flow system. The proposed method is built on the relation between the signed-distance function and the order parameter, maintaining the mass-conserved characteristic. By carefully incorporating a suitable forcing term, the target equation can be correctly recovered. Simulation results for various interface-tracking problems demonstrate that the proposed model is more numerically accurate, particularly at a small interface-thickness scale, compared to existing lattice Boltzmann models for the conservative Allen-Cahn equation.

Summary: In this study, we numerically investigate the production and transport of vorticity in two-dimensional Rayleigh-Benard convection. The flow structure and temperature distribution are found to be greatly influenced by the interaction of multiple vortices. Besides vorticity produced by wall shear stress, buoyancy also plays a significant role in generating vorticity in the bulk region. The produced vorticity is then transported through advection and diffusion. The visualization of buoyancy-produced vorticity contours allows for the observation of main and corner vortices. The correlation between the spatial distribution of vorticity flux along the wall and the Nusselt number suggests a direct relationship between the amount of vorticity entering the flow and the amount of thermal energy entering the flow.

Summary: This study applies a Lattice-Boltzmann based solver to perform scale-resolving unsteady flow simulations on a full-scale helicopter main rotor in forward flight for the first time. The validation is conducted by comparing the simulation results with reference wind tunnel data, providing insights into aerodynamic and acoustic quantities for different rotor advance ratios. Additionally, digital helicopter noise certification is achieved by calculating the ground noise map for a helicopter in landing condition.

Summary: Clean energy is urgently needed as a solution to the depletion of fossil fuel resources and increasing carbon emissions. The study investigates the flow-induced vibration and energy harvesting performance of a cylinder with attached fins. Four different configurations were tested and compared, and a bi-directional flow-energy harvester was implemented by attaching both windward and leeward fins to the cylinder. The results showed that this harvester achieved higher vibration amplitudes and had a broader velocity range compared to a plain cylinder.
