Abstract: While providing tremendous opportunities for producing and revising complex components rapidly and synthesizing advanced material architectures, additive manufacturing increases the probability of introducing defects into parts due to local and selective addition of feedstock materials. This is compounded by the complexity of multiphysics phenomena during material addition, which causes difficulties in process monitoring and prediction of final part behavior. Furthermore, the lack of standardized procedures for qualifying additive manufacturing produced parts in service critical components creates a significant bottleneck for many industries exposed to strict federal and global regulations (e.g., aerospace). To increase wide reaching application of additive manufacturing technologies, innovations are needed in improving repeatability and reliability of additive machines and processes, monitoring process health and predicting material behavior, and streamlining additive part qualification procedures. In this challenge, thermofluids and multiphysics research are integral, particularly in fluid handling processes (e.g., cold spray, wire-arc). In this talk, Prof. Özdemir will discuss how Özdemir Research Group at Northeastern University leverages thermofluids and multiphysics for: the advancement of additive manufacturing machine technology and material specific procedures in cold spray and wire arc directed energy deposition; physics informed in-situ aeroacoustic and thermal process monitoring; closing scientific gaps in thermofluids for predicting stress profiles in additively manufactured parts; and establishing feedstock and process control parameters critical for quality control in cold spray.
