Summary: The Green Deal, planned by most countries worldwide, presents a significant challenge and opportunity to shift energy production towards sustainability, environmental friendliness, and renewable sources. Hydrogen, along with renewable energy, is expected to be the green energy carrier of the future. The concept of a hydrogen economy is driving the development of new energy infrastructure to utilize renewable feedstocks instead of fossil fuels. Despite the ambitious nature, the transition from fossil fuels to a sustainable and green society has already begun, promising safer and cleaner industrial processes and improved quality of life.

Summary: The trend towards smaller structures in microelectronic, energy, and semiconductor applications has the potential to significantly improve the intrinsic properties of structures. This study examines the growth mechanisms of whiskers and the impact of surface energy on whisker formation in the Si-C-Cu system. Results indicate a correlation between hole density in the carbon layer and Cu nanowhisker density, suggesting that holes in the carbon layer could be preferred nucleation sites for whiskers, which could be relevant for future studies on nanowhisker growth.

Summary: Ice particle impact causes deformation and fragmentation, leading to the formation of a residual ice cone. High-speed video system is used to observe the impact, deformation, and fragmentation of nearly spherical ice particles, as well as measuring the size and mass of the residual ice cone. A theoretical model based on fluid dynamics is used to estimate the size of the residual ice cone, which can predict the maximum radius of impression and collision duration.

Summary: Rainbow scattering can provide information about the size, refractive index, temperature, and composition of droplets. Using a highly focused Gaussian illumination beam can improve the spatial resolution in dense spray situations. This study investigates rainbow scattering from spherical droplets and explores different inversion algorithms and the effect of beam incident position on droplet characterization. For water droplets in the size range of 50-200 μm, high accuracy in measuring the relative refractive index and small relative error in size can be achieved.

Summary: There is significant interest and demand for the multi-parameter characterization of colloidal droplets. However, optical in-situ characterization of such droplets poses a challenge due to their heterogeneous and multi-scale nature. This study proposes an analytical model for dual-wavelength extinction rainbow refractometry, which allows for the simultaneous measurement of inclusion concentration, particle size, refractive index, and droplet diameter. Validation experiments demonstrate the effectiveness of this method, and the measurement errors and limitations are analyzed.

Summary: The initial stage of solidification of a free supercooled water drop involves the formation of dendritic structures surrounded by liquid water. However, the impact dynamics and material properties of these partially frozen water drops have not been thoroughly studied. This study examines the kinematics of spreading and the geometry of the residual splat during the impact of dendritically frozen water drops. A theoretical model is then used to simulate the impact process, assuming plastic flow in the mushy drop. The model provides insights into the fluid flow near the impact axis and allows estimation of the apparent yield strength of the solid-liquid mixture for different initial temperatures.

Summary: Drop impact on a liquid film results in a new mode of splash called simultaneous corona detachment, which is caused by the breakup of the wall film. The sudden displacement of the film leads to the thinning and rupture of the corona wall, triggering propagating rims that undercut and detach the entire corona. Experimental evidence and a proposed self-consistent theory support this mechanism.

Summary: Rainbow refractometry has been developed for spray measurement applications, allowing simultaneous measurement of refractive index and droplet size. This study investigates the feasibility and accuracy of using incomplete rainbow signals for measurement. The newly defined dimensionless signal partial ratio (SPR) quantifies the degree of incompleteness. Simulation and inversion experiments were conducted, and the results showed that inversion using signal fitting is more accurate than using specific characteristic points. Laboratory experiments also verified these findings. For SPR <= 1, rainbow refractometry achieves errors within 6 x 10-4, 3% for monodisperse droplets and 2 x 10-4, 8% for spray droplets in terms of refractive index and size.

Summary: The two-sensor depth from defocus technique is developed to achieve higher spatial and temporal resolution, improve estimates of spatial size distribution and number concentration, and provide guidelines for the calibration and design of optical systems. The technique and improvements are demonstrated in the case of secondary atomization with a shock wave and a single drop, where high-resolution number density and size distributions of secondary droplets are necessary.

Summary: Spray cooling is a method used in various industrial processes and for cooling of electrical devices. The process is influenced by hydrodynamic and thermodynamic processes, and becomes more challenging when dealing with multicomponent liquids. In this study, the impact of spray onto a heated substrate was visualized and the heat transfer was characterized. The presence of a small concentration of lubricant significantly increased the heat flux and shifted the Leidenfrost point.

Summary: Ice crystal icing is a significant hazard in aviation, and accurate modeling of sticking efficiency is essential. In this study, icing wind tunnel experiments were conducted to quantify the volumetric liquid water fraction, sticking efficiency, and maximum thickness of ice layers. Two measurement techniques, calorimetry and capacitive measurements, were used to measure the liquid water content and distribution in the ice layers. The experiments showed that increasing wet bulb temperatures and substrate heat flux significantly increased sticking efficiency and maximum ice layer thickness.

Summary: Spray cooling is a technology that provides uniform and intense cooling for surfaces with complex geometry. It can be used in a wide range of surface temperatures for various applications. The performance of spray cooling depends on factors such as surface temperature, spray parameters, and the thermal properties of the liquid and substrate. This study focuses on the transitional boiling regime, which is the least studied due to its complexity. A model is developed to predict the heat flux during spray cooling in this regime and shows good agreement with experimental results.
