Experimental Pressure Traces
Heat Loss Parameters
- In the following file, initial conditions for simulation for various PC and TC are given along with the case number.
Input conditions and case numbers for simulation
- With the known case numbers, identify the heat loss parameters from the file given below, and copy the parameters to a file with the title hl.txt in the same directory which has SENKIN
Heat loss parameters for all cases
- Use the following program as the driver program for SENKIN: driver.f
- Specify initial pressure (P0), temperature (T0), composition in the SENKIN input file with VTIM keyword for calculations.
- Run the program
Note: Heat loss parameters are in the form of a polynomial. At long time after compression the polynomial may blow up to erroneous values. SENKIN calculations should be performed to a reasonable time which is sufficient for ignition to occur.
