Abstract

A naval hydrodynamics curriculum was developed within the Mechanical Engineering undergraduate program at the University of Iowa, to complement a long history of graduate research in naval hydrodynamics. The curriculum is organized into a certificate program designed to enhance students’ understanding of naval science and technology challenges, to inform students of potential career paths in or in support of the U.S. Navy, and to provide students with a firm foundation in basic concepts of naval hydrodynamics, fluid dynamics, and related experimental and computational techniques. A significant challenge is to provide students with this comprehensive background through existing and new elective courses using limited faculty resources. The Mechanical Engineering undergraduate program has not historically supported naval and marine engineering industries, and undergraduates usually do not arrive with career plans in those industries. It is therefore particularly important to the vitality of the certificate that students achieve depth in the fundamentals to ensure transferability and thus mitigate risk in students’ career planning.

Two new courses formed the foundation of the curriculum: computational and experimental naval hydrodynamics. Central to our approach in both courses was the use of complex open-ended projects employing either a proprietary naval hydrodynamics flow solver or advanced measurements in a small towing tank designed for the curriculum. Projects were structured such that students wrestle with complicated tasks that included computational model and grid generation, setup of simulations, data interpretation, uncertainty analysis, and application of advanced experimental measurement techniques such as particle image velocimetry, in order to help them develop maturity and independence in their analysis of naval hydrodynamics problems. Further, to support collaborative learning processes, class meetings consisted of frequent small group lab sessions along with lecture sessions. Both courses utilized an online forum to share knowledge and skills outside of class and provided frequent formative assessments for students to monitor their learning process to build desired skills. Both courses also provided an opportunity to interact with Navy personnel to bridge classroom learning with Navy real-world challenges.

A study was conducted to assess students’ perceptions of their competencies and learning experiences. In particular, it examined how different instructional components contributed to a positive learning experience and desired learning outcomes. 20 students from the two courses participated in the study, including four under-represented minorities and three first-generation students. A survey was administered at the end of the semester, in each course, and students’ demographic information and learning outcomes were collected after the semester was over. Students’ perceptions of achieved competency were solid; students’ assessments of their learning in the areas of fluid mechanics fundamentals, experimental, and computational methods were generally above 6 on a 7-point scale. Among instructional strategies, students reported that projects and homework using tools (e.g., the flow solver and towing tank) and the canonical models (SUBOFF, KCS, and propellers), and working in a team were the most helpful to their learning, whereas an online forum and interactions with Navy personnel, neutral. Overall, students’ perception of these courses were positive but challenging.
