In response to the global SARS-CoV-2 transmission pandemic, the Sandia National Laboratories Rapid Lab-Directed Research and Development (LDRD) COVID-19 initiative, in partnership with a multi-laboratory CARES Act research project, deployed a multi-physics, droplet-laden, turbulent low-Mach simulation tool to model pathogen-containing water droplets that emanate from synthetic human coughing and breathing events. A high-fidelity, low-Mach computational fluid dynamics (CFD) simulation tool that includes evaporating droplets and variable-density, buoyant turbulent flow coupling is well-suited... Read More
