The Research Improvement in Minority Institutions (RIMI) program was established to provide support to strengthen the research environments and capabilities of predominantly minority institutions or institutions that have substantial minority student populations. Eligible institutions must also have graduate programs in science or programs in engineering. Funding is provided for faculty research in fields of science and engineering supported by the Foundation and for the acquisition of research instrumentation. Southern University will use RIMI support to study viscous laminar flows in helicoidal pipes. The helicoidal pipe is the first basic extension of a curved pipe. Researchers will investigate the temperature field in a helicoidal pipe that is maintained under a uniform wall heat flux condition. Data collected under these conditions may be used in designing more efficient heat exchangers that require coil type heat exchange elements. The heat transfer problems will be addressed theoretically and experimentally. The principal investigator is a prolific contributor to refereed journals in the area of convective heat transfer for laminar flows in multi-passage circular pipes. The Foundation has supported this project because the participation of minorities in meritorious heat flow research will be enhanced.

少数族裔机构研究改进计划（RIMI）的设立是为了提供支持，加强以少数族裔为主的机构或拥有大量少数族裔学生的机构的研究环境和能力。符合条件的机构还必须有科学或工程方面的研究生课程。该基金为教师在科学和工程领域的研究提供资金，并为购置研究仪器提供资金。南方大学将利用RIMI支持对螺旋管内的粘性层流进行研究。螺旋管是弯曲管的第一个基本延伸。研究人员将研究在均匀壁面热流条件下螺旋管内的温度场。在这些条件下收集的数据可用于设计更有效的热交换器，这些热交换器需要盘管式热交换元件。传热问题将从理论上和实验上加以解决。首席研究员是多通道圆形管道层流对流换热领域的多产撰稿人。基金会之所以支持这个项目，是因为少数民族参与有价值的热流研究将得到加强。
