Hi All,


I have already done 1D analysis with Avl Boost.And now,I am trying to obtain some results with Avl Fire Ese Diesel. But I would ask you a question about it.My Air-Fuel Ratio is 16.86 which I saw on Avl Boost(1D analysis).But Avl Fire Ese Diesel gives me 37.4. I wrote in inital conditons on Avl Fire EseDiesel:

Egr Composition:0.0588
Egr Mass Fraction:0
Equivalence Ratio:0

How can I correct it to 16.86? The values don’t keep eachother . But total mass from 1D analysis and 3D analysis keep themselves. Please help me...

since u haven gave any equivalence ratio , fire shouldn be giving such a weird value .. can you send me your .fla file available in calculation folder to ayoshicfd@gmail.com ... i shall try my level best to sort this out

Hi,

Are you using Avl Boost? I would ask you a question about it.I can see mean pressure or total mass graphs but can not export the data of these graphs, how can ı do this? I want to obtain these datas of the graphs?

Kind Regards,

Sena

can any1 throw some light on AVL fire? so that i can link the boost engine combustion models in AVL fire or what not... what stuff AVL Fire can do where Boost cant|????

Dear All,

Although I can simulate the case with Ecfm-3z combustion model,unfortunately I can not simulate the same case with Eddy break up combustion model. What is the problem,do you think? What can I do? Please help me.

How can I compare the velocities or pressures or anything else along a line? For example; can I see the velocities at the center of the piston along center at different points? I don't know how I can do this.Please help me.

The comparisons can be made using Impress in work flow manager. There are different options in impress to make cuts which will navigate you to select the options like pressure, velocity, temp etc... A movie can also be generated in Impress. To better work with internal combustions I would go with fame engine plus It is kinda fuzzy at the beginning but you will enjoy it later on.

Thank you for your reply .I did it already. I worked with Avl Fire Esediesel module.

Hi all,

I'm working on AVL fire ese diesel module and actully I'm a very new user on it. After saving operation, I can not see my previous inputs. For example, I toggled the combustion model on and enter the all parameters and saved. But when I want to resume my model, I can not see combustion model toggle and my parameters there. But my previous engine parameters are still there but I dont know why just simulation parameters are missing.

Anyone can help me please on this ?

i am doing my final year project on cfd analysis of direct injection diesel engine. for that i need a avl fire software and i cant afford to buy that software. i am so much in need of that software so kindly request u to where can i download the software for free atleast trial version .. plz tell me if u know .. plz plz............. also suggest me other softwares to do the project.
