Week 3 - Adiabatic Flame Temperature calculation

Effect of equivalence ratio on AFT

Assume that methane is contained in a constant volume chamber. Write a program in Python to plot the effect of equivalence ratio on the final adiabatic flame temperature. Compare the results with Cantera.

Assume that N2 is present

Upload your results as a picture and provide a link to your python program (google drive or Dropbox)

You need to paste the images in your answer box and explain the results.

The correct trend for the AFT vs equivalence ratio will only be obtainable if you use the Cantera module.

2. Constant pressure reactor with heat loss

1. Consider a constant pressure reactor with heat loss. The reactor is initially set at STP conditions.

2. The heat loss should be an input in your program and must be a fraction of the "maximum possible heat loss". You will control heat loss using a variable called H_loss. Example, H_loss = 0.5 would mean a heat loss that is equal to 50% of the maximum possible heat loss.

3. The fuel type can be a general hydrocarbon of the form CxHy. Phi and lambda = 1.0. Find the AFT of CH4 with H_loss = 0.35

4. Test it only for -ane, -ene and -yne variants of 2 Carbon atom chain and plot a trend. The provided therm.dat might not contain data for other alkanes, alkynes, and alkenes (in that case use Cantera).

6. For a general alkane, plot the effect of the number of carbon atoms (from 1 to 3) on the final temperature. Assume H_loss = 0

Please upload the appropriate images, required programs and explain the results.

For comparisons between different species you are permitted to use Cantera
