Knowledge Base Repository

In addition to research papers, the Design Society is developing several valuable resources for those interested in the study of design. These include a repository of PhD theses, a library of case studies and transcripts of design activities, and an archive of our newsletters. Please note that these resources are accessible exclusively to Design Society members.

Abstract:
This study investigates the potential of multi-material additive manufacturing (MMAM) designs for improving microchannel reactors for ammonia decomposition. Using CFD simulations, designs made from stainless steel 316L and CuCr1Zr to enhance specific surface area and temperature distribution were analyzed. Results show that MMAM designs can reduce temperature gradients by up to 26.81 K and boost fuel processor efficiency by up to 3.2 percentage points compared to mono-material designs. These findings underscore the potential of MMAM in optimizing the reactor efficiency.
