Andrew Kaminsky graduated from the University of Tennessee with a Bachelor's of Science in Mechanical Engineering in 2012. During his undergraduate degree he worked extensively at Oak Ridge National Lab with the neutron facilities development division (NFDD). During a Science Undergraduate Laboratory Internship (SULI) he performed computational fluid dynamic multiphase modeling of the spallation neutron source's mercury target and performed design recommendations for bubbler locations to mitigate cavitation damage. He also collaborated with a target design team to prototype a mercury flow loop for testing at Los Alamos Neutron Science Center. During a Higher Education Research Experience (HERE) internship Andrew performed damage analysis on highly polished irradiated plates that suffered pitting damage from mercury cavitation, using laser and high-power scanning optical microscopy to analyze specimen damage. In a Nuclear Engineering Science Laboratory Synthesis (NESLS) internship he performed hydrothermal analysis of modern target designs for the spallation neutron source second target station. He used neutronics data to perform computational fluid dynamic simulations to give spatiotemporal temperature distribution in several potential target geometries.
Andrew is currently working with his advisor Kivanc Ekici to perform design optimization of turbomachinery blade geometries to improve stage efficiencies. Andrew is developing a novel design methodology utilizing computational fluid dynamics to perform iterative design optimization. He is performing turbomachinery blade optimization through gradient-based optimization methods by utilizing sensitivities found through adjoint sensitivity methods. Andrew is employing automatic differentiation methodology to determine sensitivities found through the adjoint approach within computational fluid dynamic flow solvers. He is using the harmonic balance method to perform unsteady flow analysis at a fraction of the computational cost of traditional time accurate solvers, and then implementing these solutions in a design optimization procedure.
