A state of the art pulsed laser is vital to underpin the Optical Engineering Research Group (OERG) diagnostics work in fluid mechanics and specifically our use of Holographic Partide Image Velocimetry (HPIV) which we have successfully developed in recent years. HPIV allows for mesurement of three dimensional velocity vector field maps and is used to characterise complex flow fields. Our current laser system was purchased in 1992 from an EPSRC grant, ref: GR/G55426 entitled Full-Field I.C. Engine Cylinder Flow Measurement using Partide Image Velocimetry and is now obsolete. It is important to note that the new laser will find use in more applications than we can reasonably describe in this proposal. In the three applications we have described the research will allow us to:1. better understand the flow of granular materials e.g. powders and thus prevent blockage in pumping systems and silos;2. design diesel engine combustion systems to be more efficient and environmentally friendly;3. design respiratory drug inhalers to deliver a carefully controlled drug dosage to the lungs with more efficiency.

最先进的脉冲激光对于支持光学工程研究小组(OERG)在流体力学方面的诊断工作至关重要，特别是我们近年来成功开发的全息粒子图像测速仪(HPIV)的使用。HPIV可以测量三维速度矢量场，并用于描述复杂的流场。我们目前的激光系统是1992年从EPSRC拨款购买的，编号：GR/G55426，题为使用粒子图像测速仪进行全场I.C.发动机气缸流量测量，现在已过时。值得注意的是，新激光器的用途将超出我们在本提案中合理描述的范围。在我们描述的三个应用中，这项研究将使我们能够：1.更好地了解颗粒材料(如粉末)的流动，从而防止泵系统和筒仓堵塞；2.设计柴油发动机燃烧系统，使其更高效、更环保；3.设计呼吸性药物吸入器，以更高的效率将精心控制的药物剂量输送到肺部。
