Summary: The performance optimization of electrohydrodynamics (EHD) induced heat transfer enhancement has been a subject of interest. However, comprehensive coupling optimization based on parameters such as Reynolds number, voltage, and electrode spacing is still lacking. In this study, the heat transfer efficiency of a wire-to-plate EHD device is investigated in a wide range of secondary flow intensity. The results show that an optimal secondary flow intensity and electrode spacing can significantly improve the heat transfer efficiency.

Summary: Electric energy is essential worldwide, but current energy matrices may not always be adequate. Wind energy is a viable source, although its use is limited. Centimeter-Scale Wind Turbines (CSWTs) offer a potential solution, but their design lacks a systematic procedure. This study proposes a modified approach to calculate power curves for CSWTs without the need for experimental tests. Three CSWTs were fabricated using a 3D printer and evaluated using wind tunnel testing. Results show that the modified method is well-suited for CSWT analysis, with better outcomes for turbines with more blades.

Summary: The study focuses on the feasibility of heat transfer enhancement using an external electric field, discussing the impact of corona wind on the coolant. Results show that the electric field induces a vortex that increases heat transfer rate, with the number of electrodes negatively impacting heat transfer enhancement. Additionally, the perpendicular electrode-flow layout performs better than the parallel layout.

Summary: The study found that increasing the external electric field strength and surface temperature both significantly enhance the evaporation rate of water droplets, with a special constant contact angle stage observed under the electric field. Furthermore, the evaporation enhancement mechanism may include corona wind blowing, surface tension weakening, and molecular orientational alignment, considering the effects of non-uniform electric field.

Summary: The effect of a non-uniform AC electric field on the flow regime and heat transfer performance of upward flow boiling was investigated experimentally. The experiments were conducted using HFE-7000 as the working fluid in a tubular transparent heat exchanger. It was found that low to medium AC frequencies can significantly enhance the heat transfer coefficient of initially bubbly flow, with an optimal frequency of 10 Hz.

Summary: Numerical simulations were conducted to investigate the flow characteristics inside a two-stage EHD gas pump with two electrode arrangements. The study revealed that the pump achieved improved performance by operating with three different voltage combinations. Visualization of the numerical results provided additional insight into the flowfield inside the channel. The evaluation of volume flow rate and power efficiency showed that the EHD gas pump outperformed conventional fans/pumps, making it highly promising for thermal management applications, especially when operated with uneven applied voltages.

Summary: Electrohydrodynamic drying (EHDD) is an energy-efficient and non-thermal technique for dehydrating heat-sensitive biological materials. However, little is known about the relative contribution of different dehydration mechanisms in EHDD. This modeling study identifies possible dehydration mechanisms and estimates their relative contributions, finding that convective dehydration is the dominant mechanism.

Summary: Researchers have found that wind-induced waves have a significant impact on mass transfer processes, particularly the transfer of environmental materials. These waves not only complicate wave-induced mass transport but also generate turbulence. The phase cycle of wave motion is considered a crucial factor in determining mean flow and turbulence. By using particle image velocimetry, researchers were able to measure the time-series velocity data and reveal the turbulence structure induced by wave motion. They found significant phase characteristics of energy transfer among mean velocity, wave, and turbulence components. The study also examined the diffusion and convection properties induced by wind waves through tracking analysis of imaginary sediment markers.

Summary: This text deduces a theory of gravity from the axioms of the premetric program, emphasizing the conservation of energy and momenta, the equivalence of gravitation and inertia, and the framework of purified gravity. By making the constitutive relation compatible with an action principle, the theory of coincident general relativity is uniquely fixed. The premetric formalism of purified gravity has a direct analogy with massive electromagnetism, with the metric emerging as a Stueckelberg field and the graviton as a Goldstone boson of the broken symmetry.

Summary: The appearance of van der Waals heterostructures provides a new solution to valleytronics. In this study, we observe the spin-valley depolarization process of electrons and holes in type-II MoS2-WSe2 heterostructures simultaneously for the first time, and find that they have different polarization lifetimes. The hole polarization lifetime can be prolonged to more than three times in trilayer heterostructure.

Summary: The research on EHD drying focused on designing multiple-emitter discharge electrodes by optimizing emitter type and arrangement, with emitters made of construction nails and thin pins showing the best performance. Evaluating drying efficiency through drying rate and specific energy consumption (SEC), the nail electrode with a square arrangement demonstrated the highest efficiency. Increasing electric field strength or gap between electrodes led to higher drying rates and SEC, while the chess arrangement reduced drying rate without affecting SEC.
