Abstract: A method for characterizing a process fluid comprising applying electrical power to a first resistance temperature detector (RTD) in contact with a fluid to increase the temperature of the first RTD; allowing the first RTD to cool toward a fluid equilibrium temperature; analyzing the temperature decay profile of the first RTD over time to determine thermal characteristics; applying electrical power to a second RTD in contact with the fluid to increase the temperature of the second RTD; allowing the second RTD to cool toward the fluid equilibrium temperature; analyzing the temperature decay profile of the second RTD over time to determine thermal characteristics; comparing the thermal characteristics of the first and second RTD to determining one or more characteristics of the fluid based; and performing a corrective action. The first RTD has a first coating and the second RTD has a second coating different than the first coating.

Abstract: Devices, systems, and methods within the present disclosure can assist in predicting material structural information based on functional characterization. Such predictions can be achieved by definition including a representation of a surface of a material as an ensemble of unit cells, determination of a pool of possible unit cells based on one or more material input properties, and computation of functional characteristics of the unit cells within the pool; and establishment including determination of a combination of unit cells from the pool to represent a potential surface structure of the material and computation of a corresponding cumulative functional characteristic for the material from the previously computed functional characteristics of individual unit cells of the combination, and validation of whether the computed cumulative functional characteristic matches at least one experimental measurement of the same functional property concerning the material. Iteration can assist.
