Summary: Identifying the deposition pattern of inhaled pharmaceutical aerosols in the human respiratory system is crucial for efficient drug delivery. This study investigated aerosol deposition in a patient-specific upper airway and found significant flow circulation in the nasal valve, with maximum velocity in the nasopharynx. After 2 seconds of simulation, all particles either deposited or escaped the computational domain. Larger particles mainly deposited in the nasal airway, while smaller particles deposited in the trachea.

Summary: The accuracy of a machining model is dependent on its capability to describe physical phenomena associated with real machining systems. This study developed a high-speed machining model for a titanium alloy, considering factors such as strain hardening, strain rate, and temperature. The proposed constitutive model was compared with the Johnson-Cook model and experimental data, showing closer agreement with experimental results. The use of the Coupled EulerianLagrangian approach allowed for simulation of material side flow and the formation of lateral burrs on the workpiece.

Summary: Soot generation in high-temperature biomass gasification is a significant issue, leading to air pollution and equipment contamination. The development of a comprehensive CFD soot formation algorithm, distinguishing between cellulose, hemicellulose, and lignin as soot precursors, addresses the challenge of understanding and describing the mechanisms of tar evolution and soot generation. Experimental validation and studies on biomass steam gasification provide insights into soot generation under different conditions, highlighting the potential of the algorithm in predicting and optimizing industrial-scaled biomass gasification processes.

Summary: There is currently a lack of simplified accurate source models to represent the transmission of COVID19 pathogens via airborne respiratory droplets. This study proposes an innovative framework that uses a series of relatively accurate CFD simulations to generate a dataset of respiratory events and develop a simplified source model. The results identify three main regimes of risk clouds in the transmission of viruses, which can be predicted fairly accurately by an ANN model.

Summary: Nano-fluids have attracted great attention for their potential for heat transfer improvement. The single-phase and two-phase models are used to numerically investigate the heat transfer of Nano-fluids. The single-phase approach is cost-effective and simple, while the two-phase approaches, including Eulerian-Lagrangian and Eulerian-Eulerian, offer more accurate predictions but are influenced by multiple conditions.

Summary: The Shallow Water model (SWM) is a simplification of the Navier-Stokes model (NSM) for stratified flows over a topography when the depth of the fluid layer is small compared to the horizontal scale of the flow. This study proposes a method to extend the applicability of SWM by replacing the variable topography with an apparent bottom.

Summary: The electronic structure and ferroelectric-ferromagnetic coupling properties of Y-doped and vacancy-containing GaN-ZnO heterojunctions are systematically investigated. The magnetism in vacancy-containing systems is generated by the spin polarization of unpaired electrons induced by cationic vacancies, while in Y-doped systems, bound magnetic polarons are formed by the orbital hybridization of s-state and d-state electrons of Y-doped elements.

Summary: The elementary excitations spectrum of anisotropic frustrated antiferromagnets in the fan phase is discussed. It is found that the low-energy part of the spectrum consists of a gapless phason branch with linear dispersion and a gapped optical branch corresponding to the fan structure amplitude oscillations. In the high-energy part of the spectrum, the excitations are similar to the magnons of the fully polarized phase.

Summary: In this study, the departure frequency of vapor bubbles during boiling of ferrofluid in a horizontal magnetic field is experimentally investigated. Two methods, visual and inductive, are used to measure the frequency of bubble departure. The results show that the bubble departure frequency can decrease with increasing magnetic field strength and increase with increasing temperature of the heat-emitting surface. A linear stability analysis is conducted to analyze the influence of the magnetic field on the frequency of bubble formation during ferrofluid boiling.

Summary: This study investigates the thermodynamic quantities, such as entropy, specific heat, and magnetic susceptibility, in the next-nearest-neighbors Heisenberg model on a honeycomb-kagome lattice. The linear spin-wave approach is applied to obtain the temperature-dependent behavior of these quantities. Additionally, the entanglement negativity, a quantifier of quantum entanglement, and the spin Hall conductivity are also studied. The results show that all the thermodynamic quantities, as well as the entanglement negativity and spin Hall conductivity, exhibit an increasing trend with temperature. Furthermore, it is found that all the analyzed quantities approach zero in the low-temperature limit, consistent with experimental observations.
