ADIAB95 is written in Borland, Inc.'s Turbo Pascal v 6.0, compiled for IBM PC compatible
machines. It is a DOS program, but generally is run in a DOS window under Windows 95. The
basic function and operation of ADIAB95 has not changed from that discussed in ref. 16 and will
not be repeated in detail here. However, a very brief description of operation follows.
(1) Assemble the appropriate files.in one folder. These are:
(b) SOLGAS.EXE (a renamed copy of SOL302b5.EXE)
(c) Thermodynamics data file suitable for SOLGAS and for the problem at hand
(d) Driver control file
(2) Run ADIAB95.EXE (e.g., double click its icon).
If the files were properly set up, ADIAB95 should repeatedly run SOLGAS, altering the starting
temperature for the first mixture specified in the driver control file until the adiabatic
temperature of that mixture is found. It will then repeat the process for each succeeding mixture
listed in the control file.
The format of the thermodynamics data file is described in ref. 16. Of course, the fuel and
oxidizer(s) in question presumably will be listed as starting materials. A sample file is shown in
The driver control file used by ADIAB95.EXE is a plain text (ASCII) file comprising a title line
(which will be ignored, but allows the user to label columns or include a title or description)
followed by a series of data lines, each one of which describes the parameters for a single gas
mixture. The entries on each line are, in order, as follows::
(a) Control parameter number, indicating the parameter to be varied as the adiabatic temperature
is sought. For purposes here, this should be "0" (zero), indicating that the temperature is to
(b) Starting temperature (K).
(c) Fixed pressure (bar)
(d) Initial quantity of first starting material indicated in thermodynamics data file (i.e. those
indicated by an asterisk (*) in the first column). In the file shown in Exhibit B-1, this would
be the species N2(g).
(e), (f), etc. Initial quantity of succeeding starting materials
A sample control file is shown in Exhibit B-2
