Stanford Fundamental Combustion Property Database (SFCPD)
What’s new and unique about SFCPD?
Broad coverage
SFCPD consolidates legacy data that date back to 1937. A total of 342 research articles and all listed databases were evaluated. The database covers all relevant C0-4 foundational fuels. Relevant properties include
- Laminar flame speed
- High-temperature shock tube ignition delay times
- Shock tube species time-history measurements
and selected
- Low-pressure burner stabilized flames
- Flow reactor species time-history measurements
In the FFCM-2 effort, shock tube ignition delay measurements for temperature $T$5 below 1000 K and rapid compression machine (RCM) data are not considered.
Flexible formats for both human and machines
-
The current database is hosted using the Python Data Analysis Library (pandas), which provides flexible and useful tools for data analysis and manipulation. The library is written in Python and can be readily interfaced with other Python-based softwares to automate the pipeline for kinetic model development, including Cantera for kinetic modeling, PyTorch for neural network training and Numpy/Scipy for optimization and uncertainty minimization.
-
To facilitate the human interaction with the database, we developed tools that converts the pandas database to and from the SpreadSheet, which is more human readable to allow experimentalists to share their data more easily.
Target selection
A total of 1192 targets are selected from SFCPD for FFCM-2 optimization, including
- Laminar flame speed: 408
- Ignition delay time: 749
- Flow reactor species time-history: 4
- Shock tube species time-history: 28
- Burner stabilized flames: 3
They span a wide range of thermodynamic conditions for relevant C0-C4 target fuels. The conditions can be found at the validation page.
In general, we only consider data for neat fuels as targets. Fuel blend data, including natural gas, are used for additional tests. Also, the target list only considers shock tube measurements with argon as bath gas. Data for nitrogen diluted mixtures are considered for additional tests.
