Dear friends,

I successfully simulated ESE diesel simulation with different egr rates. Now i am using multi component evaporation model to to use ethanol and diesel blends.

Parameters are as follows:

Parameters Range
Blend (% of Ethanol) 0, 10, 20
EGR (%) 0,10, 20, 30
Start of Injection 9 and 14 degree BTDC

settings employed
Initial conditions:
Multi component hydrocarbon
diesel 0.9, 0.8
ethanol 0.1, 0.2 respectively.

But in results i observed the lower calorific value 42,51, and 56 MJ/kg for diesel , 10% ethanol and 20% ethanol fuels respectively.
(I have not specified the lower calorific value and heat formation value in initial conditions blend cases) Finally it affecting IP and Indicated inefficiencies @ ESE ENGINE OUTPUT RESULTS. please help to resolve..


Your valuable advice is appreciated.
