Net-shape hot isostatic pressing of a nickel-based powder superalloy
… led to (Hf,Zr)-rich oxides and carbides on prior particle boundaries (PPBs) which could be coarsened, but not eliminated by changing the HIP procedure. HIPping above the γ′ solvus resulted in coarser grains with serrated boundaries and in the formation of irregular-shaped secondary γ′ and fan-type …

Modeling Differential Charging of Composite Spacecraft Bodies Using the Coliseum Framework
… developing a module for COLISEUM called DRACO, a particle-in-cell based code capable of plume modeling for geometrically complex spacecraft. This work integrates a charging module into DRACO. Charge is collected via particle impingement on the spacecraft surface and converted to potential. Charge …

Improving Evaporative Light Scattering Detector performance using Experiments and Modelling
… intensity). This study investigates the particle morphology and size distribution of analytes dried through an ELSD by employing multiple particle sizing techniques, including the Phase Doppler Particle Analyzer (PDPA), the Aerodynamic Aerosol Classifier (AAC), and the Scanning Mobility …

Interplay of Water Chemistry and Entrained Particulates in Erosion Corrosion of Copper and Nonleaded Alloys in Potable Water Systems
… hard water with entrained aragonite (CaCO3) particles could cause fully penetrative failures (i.e., leaks) in brand new copper pipe and nonleaded brass fittings in just 3-49 days. This represents the first time rapid erosion corrosion failures have ever been replicated in the laboratory under …

Flow Induced Failures of Copper Drinking Water Tube
… concentration cell corrosion, cavitation, particle/bubble impingement and high velocity impingement. Concentration cell effects resulting from exposing different copper surfaces to different flow regimes created a strong electrochemical cell that caused rapid corrosion that persisted for …
