Light sheet fluorescence microscopic imaging for the primary breakup of diesel and gasoline sprays with real-world fuels
This paper details the adaptation of laser-induced fluorescence for studying the primary breakup of diesel and gasoline direct injection sprays using a microscopic technique and special tracer dyes for high-quality imaging. The phenoxazine dye Nile Red was identified as an effective tracer due to its solubility in alkanes and suitable emission spectrum, enabling clear single-shot images of spray structures. Compared to other techniques, light sheet fluorescence microscopic imaging offers a balance of complexity and excellent data quality on spray structures and fuel distribution.
Advancing Fuel Cell Testing Environments: Overcoming Limitations in Conventional Humidification Methods
In the field of polymer electrolyte membrane fuel cells (PEMFC), optimizing the fuel cell system (FCS) design requires careful monitoring of various process parameters, with relative humidity being particularly critical. Current test stands lack the capability for high throughput testing with sufficient data accuracy, highlighting the need for improved testing environments. This paper evaluates the limitations of conventional humidification methods and proposes precise mass flow control of water as a solution for more accurate and efficient testing.
This study explores the effectiveness of immersion cooling for EV batteries, emphasizing the design requirements for heat-transfer liquids with high electrical resistivity, thermal conductivity, and low viscosity. Key concepts include enhancing heat transfer through vortical motion in laminar flow and stabilizing vortices with viscoelastic agents. The research involves characterizing viscoelastic flow using Particle Image Velocimetry (PIV), measuring heat transfer with an Atom Layer Thermopile (ALTP) sensor, and conducting CFD modeling. Results indicate improved heat transfer with high-viscosity liquids, though further experiments are needed to confirm the trend.
This study utilizes high-speed Diffuse Back Illumination Extinction Imaging (DBI-EI) to measure projected liquid volume (PLV) in a transient GDI process, using a LED panel for illumination and an ECN Spray G injector. The technique faces challenges with scattering effects, leading to underestimation of optical depth and PLV. A simulation-based correction method is proposed, improving accuracy and enabling three-dimensional reconstruction of liquid volume fraction, while maintaining low experimental effort.
