ACME CFI-G — Advanced Combustion via Microgravity Experiments / Cool Flames Investigation with Gases
Hardware: ACME, Combustion Integrated Rack (CIR) · Program: International Space Station (ISS) · Fuel phase: Gas · DOI 10.60555/cyt1-kh64
Objective
1. Plan and support flight testing on the International Space Station (ISS). 2. Determine the conditions for which cool diffusion flames occur for propane, n-butane, and n-pentane; normal and inverse flames; and a broad range of Zst, Tad, and fluent flow rate. 3. Support the flight tests with advanced CFD simulations. 4. Identify or develop a chemical kinetics mechanism that yields good agreement between the CFD predictions and the ISS measurements. 5. Disseminate the results as widely as possible.
ACME CFI-G (PSI-159, ACME, Combustion Integrated Rack (CIR), International Space Station (ISS)). 333 test runs from NASA PSI (DOI 10.60555/cyt1-kh64).
