0846359白色更好地了解壁面边界湍流中液化生物质的基本流体物理对于生物炼油厂的放大和生物质管道的设计具有重要的实际意义。这两项都是实现美国生物燃料目标所必需的，该目标是为全国30%的交通燃料提供生物燃料。为了达到项目的目标，PI计划提高超声相关测速的时间和空间分辨率，评估液化生物质流体的流变性和结构，并表征壁面边界的生物质湍流流动。这些研究将提供以前无法获得的信息，从而能够预测在壁面边界湍流中液化生物质的输送情况。能源部门技术方面的动荡的作用将是教育和外联活动的主题。根据研究主题，目标是通过工业研究机会、研讨会和推广活动教育学生和教育工作者，了解湍流的影响及其控制对当前和未来的能源系统至关重要。这项研究的更广泛影响是获取和转让基础知识，以便在美国更多地使用“本土”可再生燃料；获得和改进UCV系统，使其能够研究各种其他流变性、多相、不透明流体流动问题；以及吸引和培养对能源、湍流和复杂流体领域感兴趣的高素质学生。教育和研究活动的整合是通过为PI的研究生提供工业研究机会、丰富教学大纲、K-12外展、继续教育，以及通过实验室参观和演示参与大学外展日来实现的。最后，PI将积极招募目标少数群体到他的实验室工作，并通过项目Reis@UNH(在UNH的科学研究经验)，这是该大学与哈莱姆儿童协会的合作项目；并在几个针对少数群体的出版物上张贴帖子。

0846359 WhiteBetter understanding of the fundamental fluid physics of liquefied biomass in wall-bounded turbulent flows is of practical importance for the scale-up of biorefineries and the design of biomass pipelines. Both are needed to accomplish the United States biofuel objective of providing 30% of the nation's transportation fuels with biofuels. To meet the goals of the project, The PI plans to improve the temporal and spatial resolution of ultrasound correlation velocimetry, evaluate the rheology and structure of liquefied biomass fluids, and characterize wall-bounded turbulent biomass flows. These studies will provide previously unobtainable information that will enable predictive estimations of the transport of liquefied biomass in wall-bounded turbulent flows. The role of turbulence in energy sector technologies will be the theme of the educational and outreach activities. Drawing on the research topics, the objective is to educate students and educators through industrial research opportunities, workshops, and outreach that understanding the effects of turbulence and their control is critically important to current and future energy systems. The broader impacts of the research are to acquire and transfer fundamental knowledge to allow greater use of 'homegrown' renewable fuels in the US; acquire and improve a UCV system allowing the study of a variety of other rheological, multiphase, opaque fluid flow problems; and attract and train highly qualified students interested in the fields of energy, turbulence, and complex fluids. Integration of education and research activities is achieved by offering industrial research opportunities for the PI's graduate students, syllabus enrichment, K-12 outreach, continuing education, and participating in University outreach days by including lab tours and demonstrations. Lastly, the PI will actively recruit target minorities to work in his labs and potential Ph.D. students through Project REIS@UNH (Research Experience In Science at UNH), a collaboration between UNH and the Harlem Children Society; and postings in several publications targeting minority populations.
