CAREER: Experimental studies of the rheology and flow properties of liquefied biomass in wall-bounded turbulent flows

更好地了解壁面湍流中液化生物质的基本流体物理对于生物精炼厂的规模化生产和生物质管道的设计具有重要的实际意义。要实现美国的生物燃料目标，即为全国30%的运输燃料提供生物燃料，这两者都是必需的。为了实现该项目的目标，PI计划提高超声相关测速的时空分辨率，评估液化生物质流体的流变学和结构，并表征壁面湍流生物质流动。这些研究将提供以前无法获得的信息，这些信息将使液化生物质在壁面湍流中运输的预测估计成为可能。动荡在能源部门技术方面的作用将是教育和外联活动的主题。根据研究课题，目标是通过工业研究机会，研讨会和外展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移基础知识，以便在美国更多地使用“本土”可再生燃料；获得并改进UCV系统，允许研究各种其他流变、多相、不透明流体流动问题；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。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示范参与大学外展日，实现了教育和研究活动的整合。最后，PI将积极招募目标少数民族到他的实验室工作，并通过UNH与哈莱姆儿童协会合作的REIS@UNH （UNH科学研究经验）项目招收潜在的博士生；在一些针对少数族裔的出版物上发表了文章。

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.
