Category   : Tools

Files Included:
  - gas_mixture.f90 (Fortran Source Code)
  - input.txt (Pre-configured Sample Input)

-------------------------------------------------------------------------
1. How to Compile
-------------------------------------------------------------------------
Make sure you have a Fortran compiler installed (like gfortran).
Run the following compilation command in your terminal:

  gfortran -O3 gas_mixture.f90 -o gas_mixture

-------------------------------------------------------------------------
2. How to Execute
-------------------------------------------------------------------------
Run the compiled binary and redirect the input.txt file into stdin:

  gas_mixture < input.txt

-------------------------------------------------------------------------
3. Input File Details
-------------------------------------------------------------------------
The input file 'input.txt' contains sequential parameters separated by
newlines. Here is the structure of the included 'input.txt':

  Line 1 (Number of species in mixture (up to 10)): 2
  Line 2 (Species 1 mole fraction): 0.79
  Line 3 (Species 1 molar mass [g/mol]): 28.01
  Line 4 (Species 1 molar heat capacity Cp [J/mol-K]): 29.1
  Line 5 (Species 1 dynamic viscosity [uPa-s]): 17.8
  Line 6 (Species 1 thermal conductivity [W/m-K]): 0.0260
  Line 7 ((Repeat inputs sequentially for each species)): 0.21
  Line 8 (Parameter 8): 32.00
  Line 9 (Parameter 9): 29.4
  Line 10 (Parameter 10): 20.6
