Automatic Design of Transport Systems Through Topology Optimization on Adaptively Refined Computational Grids
Victor Beck | 19-ERD-035
Transport systems are technologically important across industry, engineering, and science. These systems are characterized by the flow of material and energy, include thermally and electrochemically driven reactions, and touch diverse applications including heat exchangers, absorbers, chemical reactors, batteries, process equipment, manufacturing, transportation, etc. The simultaneous occurrence of multiple physical phenomena makes the design of these systems especially challenging. Computational tools to simulate the performance of these systems exist, but there are limited tools to automate the design process. This project thus focused on applying computational design optimization to automatically design transport systems.
The first objective was to develop the formulation to allow for the architectural optimization of the transport problems and then to implement these into a computational design framework. The latter was accomplished using a combination of internal and opensource simulation and optimization tools. At its core, this framework is a combination of a forward simulation, a sensitivity calculation, an optimization, and an interface to connect these calculations. This results in the development of new solution techniques and general purpose software for parallel simulation and optimization. The second objective was to improve the accuracy of the calculations via adaptively refine grids. The principal outcome was a preliminary effort on using goal oriented mesh refinement to efficiently, and automatically, increase the mesh density at phase boundaries. Lastly, the framework was utilized for the automatic design of flow batteries, heat exchangers, flow manifolds, porous electrode, electric double layer capacitors, and thermal catalytic reactors, thus introducing architectural and topology optimization as a viable tool across transport system applications.
This project grew Lawrence Livermore National Laboratory's (LLNL's) competency in the topology optimization of non-structural systems, and focused specifically on demonstrating and extending the use of existing techniques and tools at the Laboratory to create a new competency in the design of transport systems. This work has thus figured into multiple follow-on proposals, including external CRADAs with energy companies (TotalEnergies, OxEon, and Twelve), and is a component of DOE grants for the design of bioreactors and fluid manifolds for electrochemical reactors. This work thus addresses DOE's energy and environment missions, providing a new capability and tool to determine innovative solutions. Additionally, this work supported several new scientific hires with core expertise in High Performance Computing, Optimization, and Applied Math. The efforts of this proposal will continue addressing research needs for the design of transport systems across projects at LLNL, DOE, and industry.
