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.

0846359 White更好地理解壁边界湍流中液化生物质的基本流体物理学对于生物精炼厂的规模扩大和生物质管道的设计具有实际重要性。这两项都是实现美国生物燃料目标所必需的，即为全国30%的运输燃料提供生物燃料。为了实现该项目的目标，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学和结构，并表征壁边界湍流生物质流。这些研究将提供以前无法获得的信息，这将使预测性估计的运输液化生物质在壁边界的湍流。能源部门技术动荡的作用将是教育和宣传活动的主题。根据研究主题，目标是通过工业研究机会，研讨会和宣传教育学生和教育工作者，了解湍流及其控制的影响对当前和未来的能源系统至关重要。该研究的更广泛的影响是获取和转移基础知识，以允许在美国更多地使用“本土”可再生燃料;获取和改进UCV系统，允许研究各种其他流变，多相，不透明的流体流动问题;并吸引和培养对能源，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，教学大纲丰富，K-12推广，继续教育，并通过包括实验室图尔斯和演示参加大学推广日来实现的。最后，PI将积极招募目标少数民族在他的实验室工作，并有可能获得博士学位。通过联合国大学与哈莱姆儿童协会的合作项目REIS@UNH（UNH科学研究经验），为学生提供信息;并在几个针对少数群体的出版物上发帖。
