Abstract: Fluid flow systems can include one or more resistance temperature detectors (RTDs) in contact with the fluid flowing through the system. One or more RTDs can be operated in a heating mode and a measurement mode. Thermal behavior of the one or more RTDs can be analyzed to characterize a level of deposit formed on the RTD(s) from the fluid flowing through the system. Characterizations of deposition on RTDs operated at different temperatures can be used to establish a temperature-dependent deposition profile. The deposition profile can be used to determine if depositions are likely to form at certain locations in the fluid flow system, such as at a use device. Detected deposit conditions can initiate one or more corrective actions that can be taken to prevent or minimize deposit formation before deposits negatively impact operation of the fluid flow system.

Abstract: A non-contacting aerodynamic jet tool for collecting particles and vapors associated with surfaces. Opposing planar jets or planar jet arrays are used to liberate material from surfaces so that resuspended particulate matter and vapors can be collected for analysis. In operation, high-speed valves are triggered to create waveforms of high velocity pressurized planar jet bursts. The wall jets that traverse the surfaces exhibit unexpectedly high wall surface stress with velocity spikes characteristic of a chain of shock waves. Unlike axisymmetric jets, the wall jet tool flows over the target surface for a greater distance with wall shear stress having sufficient momentum to dislodge particles submerged in the boundary layer, dramatically improving sampling efficiency by lifting the particles and vapors from the boundary layer into a sampling intake for downstream analysis.
