Problem 1
Turns 2.52. Use a chemical equilibrium package.
Problem 2
Compare the adiabatic flame temperature for methane/air combustion to methane/oxygen combustion. Do this for adiabatic constant pressure (HP), and for adiabatic constant volume (UV).
Problem 3
Read the notes and code for the element potential method for chemical equilibrium. Just state if you did this.
Problem 4
Compute the LHV for methane combustion using equilibrium products to the LHV given in Turns, which assumes products of complete combustion.
Problem 5
Turns 2.47
Problem 6
Consider a spark ignition engine with a compression ratio of 10, fed with a stoichiometric propane/air mixture. The temperature of the premixed propane/air in the inlet is 300 K. Compute the net work done by an ideal engine per kg of fuel. Also compute the efficiency on an LHV basis. What is the equilibrium NO at the end of the combustion step, and at the end of the expansion step?
