A Small Research Facility for Multi-phase Flows at High Pressure and Temperature

爱丁堡大学正在购买一个稳定的流量，高压（P < 120 bar）和温度（T < 1000 K）光学可及的射流和喷雾研究室。这个商会在英国是独一无二的。此外，该大学还购买了一台单缸光学研究引擎。该室可用于研究各种喷雾；它们是如何发展和反应的。该发动机可用于研究瞬态燃油喷射与真实缸内流动的相互作用。有了这笔拨款，爱丁堡大学将获得高度先进的激光诊断，用于新腔室和发动机以及其他相关实验设备的多参数测量，作为利用大学大量设备投资（140万英镑）的一种手段，进入英国范围内的小型研究设施（SRF）。该SRF要获得的测量包括：a)飞秒激光系统和辅助设备（如二次谐波带宽压缩系统（SHBC），频率分解光门控（FROG）表征脉冲等）。该系统将用于混合皮秒/飞秒旋转CARS（相干反斯托克斯拉曼光谱），用于喷射/喷雾设备中的线像温度和物质（例如O2， N2， H2等），以及用于研究高度雾化喷雾中初级破裂的弹道成像。b)高速（HS） 2脉冲，532 nm波长激光和HS成像系统，用于HS立体PIV， SLIPI成像，LII用于颗粒。一个HS 1脉冲，355/ 266nm波长激光器和HS增强系统，用于HS PLIF，荧光粉和LITA。c)用于反应射流和喷雾中液滴/颗粒尺寸分布和速度的相位多普勒仪器。该组合设备和诊断将使以下方面的新研究成为可能：A)燃料喷雾（包括替代燃料）和b)超临界材料合成（生物燃料，药物，纳米催化剂，聚合物等）。我们的研究目标是多方面的。这项研究将使更高效的内燃机成为可能，减少它们对气候的影响。它还将使理解和改进材料合成的超临界工艺成为可能，有助于更有效地将此类产品推向市场。通过这样做，我们将满足英国既有产业和关键新兴产业的关键需求。

The University of Edinburgh is purchasing a steady flow, high pressure (P < 120 bar) and temperature (T < 1000 K) optically accessible jet and spray research chamber. This chamber is unique within the UK. In addition, the university is also buying a single-cylinder optically accessible research engine. The chamber can be used to study sprays of all kinds; how they develop and react. The engine can be used to study transient fuel sprays as they interact with realistic in-cylinder flows. With this grant, the University of Edinburgh will acquire highly advanced laser diagnostics for multi-parameter measurements in the new chamber and engine, and in other related experimental devices, as a means to leverage the university's substantial equipment investment (£1.4 million) into a UK-wide Small Research Facility (SRF). The measurements to be acquired by this SRF include:a) A femtosecond laser system and ancillary devices (e.g. a second harmonic bandwidth compression system (SHBC), frequency resolved optical gating (FROG) to characterize the pulses etc.). The system will be used for hybrid picosecond/femtosecond rotational CARS (coherent anti-Stokes Raman spectroscopy), for line-image temperature and species (e.g. O2, N2, H2 etc.) in the jet/spray equipment, and ballistic imaging for investigation of primary breakup in highly atomizing sprays.b) High-speed (HS) 2-pulse, 532 nm wavelength laser and HS imaging systems for HS stereoscopic PIV, SLIPI imaging, and LII for particulate. A HS 1-pulse, 355/266 nm wavelength laser and HS intensifier system for HS PLIF, phosphors, and LITA. c) A phase Doppler instrument for droplet/particle size distribution and velocity in reactive jets and spraysThe combined equipment and diagnostics will enable new studies on:a) Fuel sprays (including alternative fuels), and b) Supercritical materials synthesis (biofuels, pharmaceuticals, nano-catalysts, polymers etc.). Our research goals are multi-faceted. The research will enable more efficient combustion engines, reducing their impact on the climate. It will also make it possible to understand and then improve supercritical processing for materials synthesis, helping bring such products to market more effectively. In so doing we will address critical needs for both established industries and for key emerging industries across the UK.
