Key Responsibilities * High-Velocity Nozzle Design: Design, machine, and test custom Convergent-Divergent (Laval) nozzles to achieve controlled gas expansion for both liquid filament breakup and high-shear solid deagglomeration. * Multiphase Dispersion: Develop and optimize systems for the simultaneous or alternating dispersion of complex liquid aerosols and dry-powder "seeds" using high-velocity gas streams. * Hardware Prototyping: Build mechanical dry-powder micro-feeders, liquid delivery architectures, and aerosol generators from the ground up, utilizing high-pressure gas supply systems. * Fluid/Mechanical Architecture: Develop the pneumatic and fluidic routing systems (valves, regulators, and micro-channels) required to maintain specific pressure ratios necessary for choked flow and stable supersonic jets. * UAS Integration: Adapt benchtop aerosol generation concepts into lightweight, battery-efficient payloads capable of surviving flight vibrations and high aerodynamic shear. * Rapid Iteration: Work collaboratively to evaluate hardware performance and rapidly iterate nozzle geometries based on empirical droplet-size and particle-size data. Required Qualifications * BS, MS, or PhD in Mechanical Engineering, Chemical Engineering, or a closely related technical field. * Approximately 5 years of hands-on experience in mechanical engineering, specifically focused on fluid dynamics, multiphase flow (gas-liquid/gas-solid), or atomization. * Proven experience in Mach number optimization, internal nozzle flow, and the physics of choked flow conditions. * Proven experience physically building and troubleshooting fluidic or pneumatic hardware (e.g., high-velocity gas jets, Laval nozzles, precision sprayers, or powder dispersers). * Understanding of droplet dynamics and breakup regimes (e.g., Weber number effects) and techniques for nanoparticle deagglomeration. * Strong CAD proficiency (SolidWorks, Fusion 360, etc.) and hands-on hardware prototyping experience, including CNC machining and general fabrication. Preferred / Bonus Qualifications * High-Speed Flow Characterization: Experience with the analysis of high-velocity particulate exhaust, liquid-jet disintegration, or supersonic multiphase flows. * Advanced Particle & Droplet Dispersion: Familiarity with kinetic aerosolization techniques where liquid or solid phases are accelerated to high velocities for fragmentation or dispersion. * Computational Modeling: Experience with CFD (e.g., ANSYS Fluent, COMSOL) to model droplet/particle trajectories, velocity lag, and shock-wave interactions in high-speed plumes. * Aerosol Instrumentation: Familiarity with standard analytical tools such as Malvern Spraytec, SMPS, or optical particle counters for characterizing both sub-micron liquid and solid aerosols. * Basic proficiency in electronics prototyping (Arduino, Raspberry Pi) and software/scripting (Python) for hardware control and data acquisition.
