About the role
Overview
Roadrunner Venture Studios is seeking a contract Subject Matter Expert (SME) to develop and execute an experimental test program for a proprietary nozzle for the generation of two-phase flow targeting intermediate-temperature energy systems. The primary objective is to establish a reliable, repeatable methodology for thrust measurement, characterize the two-phase flow exiting the nozzle, and reduce system variables so testing is focused on nozzle performance.
Scope of Work
The contractor will: • Develop and execute a test plan for a two-phase nozzle operating with geothermal working fluids and experimental refrigerants. • Design and validate a reliable thrust measurement system. • Characterize the spray leaving the nozzle, including gas-to-liquid ratio, droplet concentration, droplet distribution, and mixed-phase flow behavior. • Measure and analyze flow characteristics, pressure, temperature, and other critical performance parameters. • Reduce experimental variables to isolate nozzle performance and improve test repeatability. • Recommend and implement instrumentation and test fixtures required to produce high-confidence data. • Analyze results and provide recommendations to improve nozzle performance and overall test methodology.
Preferred Qualifications • M.S. or Ph.D. in Mechanical Engineering or related field preferred. • Hands-on experience with two-phase flow, organic rankine cycle systems, refrigerant testing, or nozzle/thrust measurement. • Strong experimental background with fluid systems, instrumentation, and test development. • Experience with compressor and refrigerant line design, HVAC or process engineering, or propulsion testing is highly desirable. • Ability to travel to Albuquerque, New Mexico, to support testing.
