Experimental and Theoretical Investigations of Diffusion of Gases Through Porous Media

改善少数民族机构研究方案旨在通过提供支持，加强以少数民族为主的机构的研究环境和能力，增加少数民族对科学和工程研究的参与。有资格参加这个项目的机构除了必须招收大量的少数民族学生外，还必须有科学或工程专业的研究生课程。北卡罗来纳农工州立大学将利用RIMI的支持建立一个研究小组，研究气体在多孔介质中的扩散。通过模型多孔结构的气体通量的实验和理论研究将从克努森极限到整体扩散极限进行。将对四种模型多孔介质结构进行表征，并在广泛的温度和压力范围内确定He， N和CO的扩散速率。流动方程将基于两个数学模型。利用实验数据优化的数学模型将提供描述真实多孔介质参数的基本信息。这个研究多孔介质中扩散的项目是合理的，特别适合本科生和研究生的研究，应该会产生有用的数据。组建的研究小组是平衡的，每个提议者都在自己的专业领域胜任。该项目在加强工程研究的长期计划方面具有极好的潜力，并将加强北卡罗来纳农工州立大学学生和教职员工的研究能力。

The Research Improvement in Minority Institutions (RIMI) program was designed to increase the participation of minorities in scientific and engineering research by providing support to strengthen the research environment and capabilities of predominantly minority institutions. Institutions eligible to participate in this program must have in addition to a substantial enrollment of minority students, graduate programs in science or programs in engineering. North Carolina A&T State University will use RIMI support to establish a research group to investigate the diffusion of gases through porous media. Experimental and theoretical studies of gas fluxes through model porous structures will be conducted from the Knudsen limit to the bulk diffusion limit. Four model porous media structures will be characterized and diffusion rates of He, N and CO determined over a wide range of temperatures and pressures. Flow equations will be developed based on two mathematical models. Mathematical models, optimized by use of experimental data will provide basic information about the parameters that describe true porous media. This project to study diffusion in constructed porous media is sound, particularly well adapted to undergraduate and graduate research and should yield useful data. The assembled research group is balanced and each of the proposers is competent in their own area of expertise. The project has excellent potential for enhancing long-range plans for engineering research and will strengthen student and staff research capabilities at North Carolina A&T State University.
