Full Description
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.
