Accessing the Data
This document is available in three forms: as a LaTeX typeset postscript
file, as a PDF (portable document format) file, and as HTML.
The online version is accessible
at the URL http://www.galcit.caltech.edu/detn_db/html/.
The postscript version (1.83 MB) and
pdf version (1.02 MB) can be downloaded
from the WWW, through the HTML version.
The printable and online formats contain the same information with somewhat
For instance, the printed document is more readable, but the WWW version
offers a search engine.
The data are organized into three main sections that are linked
together. The summary graphs represent a compilation of typical
data organized in terms of type of fuel/oxidizer/diluent and
category of data. Many inquiries may be satisfied by one of the
plots. These plots are generated from, and refer to, the data
tables. The numerical values in the data tables are available
for reduction and inclusion in further graphs. Each data table
is referenced to one of the sources listed in the References
section, which stands alone as a useful bibliography of detonation
The data sets are organized into a number of categories, some with a set of sub-categories.
We are trying to put all the data in consistent units, at least
for the sake of the summary graphs. The data tables (generally) contain the
original units as presented in the literature along with our
Following are abbreviations for all the journals and
serials mentioned in the References. Wherever possible, they are based on
the recommendations of the Bibliographic Guide for Editors and Authors,
published by the American Chemical Society (1974).
Pitfalls and Hints
When searching the database for a particular item, there are several
pitfalls to avoid and hints that can help you:
- Appropriate data points may be found in unexpected places.
Each data set represents a set of measurements as some variable (initial
pressure, equivalence ratio, etc.) is varied, while other variables are
held constant. Therefore, different data sets may overlap but not be
presented together. Also, Air is considered an oxidizer, but will
generally not be found during searches for O2 or N2.
- When using the search engine, unwanted information may be found.
Of course, this is preferable to not finding wanted information, but can
be a hassle. For instance, searching for H2 will also find C2H2.
- Temperature information are frequently lacking in experimental
reports, even though it is very important as a modeling parameter. In cases
where the temperature is not reported but is presumably "room temperature",
293 K is listed in the database.
- Data in the literature are often reported along with error bars.
Only nominal values are currently contained in this database. Error
analysis information must be obtained from the original references.
