Justin Weinmeister is an associate nuclear fluid mechanics engineer in the Energy Systems Development group of the Fuel Cycle Science and Technology Division at Oak Ridge National Laboratory. His research focuses on the verification, validation, and uncertainty quantification of computational fluid dynamics (CFD) models for complex systems. He has additional experience in experimental fluid mechanics, heat transfer, and optimization. At ORNL, his work has included re-design of the Spallation Neutron Source (SNS) mercury target for the proton power upgrade, coolant channel design for the Transformational Challenge Reactor (TCR), component design for the Materials Plasma Exposure eXperiment (MPEX), and tokamak divertor optimization. Professionally, he serves on the American Society of Mechanical Engineers’ (ASME) subcommittee for Verification and Validation in Computational Fluid Dynamics and Heat Transfer (VVUQ 20) and is an organizer for technical sessions in computational fluid dynamics and multiphase flow for the AMSE’s Fluids Engineering Division. Justin is also the developer of CFDverify, an open-source Python library designed to assist computational scientists.
