This paper shows a project by three honors students in an undergraduate engineering program. Students used a 3D printer to fabricate a wing section of the NACA 2412 airfoil. The section has a chord length of 230 mm and a total assembled width of 305 mm. The wing was printed in three separate, hollow sections including a 25mm wide inner section and two 140mm wide outer sections assembled on each side of the inner section. The inner section contained 36 surface holes that were attached by copper tubes and Tygon tubing connected to a multi-manometer. The experiments were compared with CFD simulations using ANSYS Fluent software. Detailed descriptions of the experimental design, fabrication, set-up, learning process and cost are included in the paper together with links to tutorials to repeat the experimental setup as well as a tutorial of the mesh generation and settings for the CFD simulations. Finally, the paper will provide a description of the outcomes for the project, student involvement and response, and an assessment of the student learning procedure.
He has been teaching science and engineering courses there for 26 years, and is a registered Professional Engineer in the State of Oklahoma. He received BS and MS Degrees in Aeronautical and Astronautical Engineering from Purdue University in 1985 and 1986, and a PhD in Mechanical Engineering from UCLA in 1992. He received an MA Degree in Biblical Literature from Oral Roberts University in 2013. His current research interests involve the use if virtual reality for engineering education, the integration of faith and learning, contributions from the field of engineering to the current science/theology discussion, reverse engineering of complex natural systems, and the preparation of scientists and engineers for missions work within technical communities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
