Consider a jet engine burner that operates at an air mass flow rate of 50 kg/s where the burner inlet conditions (state 3) are 2 MPa and 700 K. Combustion in the burner can be described by a serial combination of fuel droplet evaporation (with a D-squared evaporation rate of k = 5 10^-6 m2 /s), followed by fuel-air mixing (time constant of 0.1 ms), followed by combustion chemistry (time constant of 1 ms). Find the minimum internal volume for the burner that will allow complete combustion for two different fuel injectors, one that produces atomized fuel droplets with diameters of 10 m and another that produce droplets with diameters of 100
