Darius Lisowski manages the Reactor Safety Testing & Analysis group within Argonne’s Nuclear Science and Engineering Division. His primary research area is in experimental thermal hydraulics with a focus on natural circulation systems and two-phase flow. He also has extensive experience with the development and use of high-fidelity sensors, data acquisition, and control systems. He is currently the principal investigator for the Natural Convection Shutdown Heat Removal Test Facility (NSTF) at Argonne, and had led the conversion to a water-based cooling design. In addition to experimental practices, he has carried out extensive studies on scaling criteria, instability modes, and computational model with both system level and CFD codes.
