biodiesel operated diesel engine simulation-is it possible?

jaycee · August 14, 2011, 01:28

Hi everybody!

I want to simulate a diesel engine using biodiesel as fuel.Is it possible to carryout the combustion analysis with the available combustion model in star-cd.One of my friend who knows CFD says combustion anlaysis of biodiesel fuel cannot be carried out using star-cd.Is it correct.If correct how can i simulate.I am eagerly expecting for your replies.

Thanking you

With Regards

What reason(s) did your friend cite?

Off the top of my head, I can not think of a reason why the StarCD models are not as suited to biodiesel as they are to "regular" diesel. You will have to update all the appropriate fuel properties.

He says that STAR-CD combustion model was developed for hydrocarbons(like diesel or petrol) and not for oxygenated fuels like biodiesel. since the combustion (chemical) reactions of biodiesel are different from diesel we cannot use any combustion model of STAR-CD.

i want to know whether you still simulate biddiesel combustion?
