The Applied Chemicals and Materials Division (ACMD) of the NIST Material Measurement Laboratory (MML) carries out measurement science research in high-impact science and engineering fields that utilize vapors and liquids.  Our experimental scientists focus on developing fundamental measurements and novel methodologies that can characterize  complex fluids and their interaction with other matters.  However,  measurements require interpretation that is aided by computational fluid dynamics (CFD) and computational fluid particle dynamics (CFPD) modeling.  Such virtual experiments become tools to provide a deeper understanding of the measurements as well as discerning strategic laboratory test setup and analysis by the quantification of the uncertainties encountered in the physical experiments.  These computational methods have been applied to nanorheology in photopolymerization 3-D printing [1], human breath research for forensic and clinical data, vapor-liquid equilibrium analysis [2], and micro-electro-mechanical systems (MEMS) devices such as micro-pumps.  This is an opportunity for candidate familiar with CFD methodology to apply their knowledge in a wider field of physical phenomena and their associated measurements.
