This honors project covers two subjects in conjunction with an engineering capstone project to design a self-centering labyrinth seal for centrifugal compressors. The first subject covers writing a guide to "Design for X" intended for use by future engineering seniors at Smith College. DfX is a holistic design strategy of identifying specific design constraints from downstream aspects of a product development lifecycle (eg. manufacturing, distribution, service) and utilizing them in early development to develop better products, processes and systems. The guide covers the overarching concepts of DfX and delves into Design for Assembly, Design for Manufacturing and Design for Prototyping as examples of DfX guidelines. The guide focuses on strategies to identify and tailor DfX strategies to their specific projects. The second subject is an actual prototype of the labyrinth seal which serves as an addition to the capstone project deliverable as well as an application of the Design for Prototyping concepts covered in the guide. The prototype will be sent to Dresser-Rand's facility in Olean, NY to test on an existing compressor test rig.
