Hi

I would like to simulate the variation in injection time schedule in a Diesel engine.

I remember that in OF-1.4.1-dev there used to be a DieselEngineFoam solve, but it is no longer present in OF-2.0.1

I have checked and there is no OF-2.0.1-dev release either, can someone please tell me where to find the latest OF-x-dev release, and how to compile it...?

The one i have presently in my PC is the 2.0.1 release, and has been compiled with Icc compilers...

Thanks in advance.

Greetings Alex,

If you do have 2.0.1 installed:

• Solver code is located here: $WM_PROJECT_DIR/applications/solvers/combustion/dieselEngineFoam
• Solver binary is located here: $FOAM_APPBIN/dieselEngineFoam
• There are no tutorials that use this solver in OpenFOAM 2.0.1.

Now, since you mentioned 1.4.1-dev, then you should be looking for 1.6-ext, which is provided by the Extend Project: http://www.extend-project.de/
Instructions for installing that version: Short tutorial for installation OpenFOAM®[-Extend]

For more about the differences between the original version and the Extend Project version, see here: How do the OpenFOAM versions differ?

I've just checked 1.6-ext and the solver is placed in the same place; and I didn't find a tutorial for it either.

Keep in mind that in Linux DieselEngineFoam is not the same as dieselEngineFoam
Linux (usually) uses a letter case sensitive file system, while Windows and Mac OS X use a letter case preserving file system. The reason is pretty simple: Windows and Mac OS X pride themselves in being user friendly, while Linux prides itself in doing things the right way :P ... And when it comes to CFD, you better do things the right way, or else...

Best regards,
Bruno

Hi Bruno

Thanks

I know that in *nix, Diesel* is different from diesel*, it was just a typo...

Anyway, I think i will try to build a tutorial out of dieselFoam and engineFoam definitions, but i guess engineGeometry is different and incorporates the definitions of injectorProperties from dieselFoam...

Will have to search a bit on this...

Anyway, thks a lot

I want to simulate dual fuel diesel engine with OpenFOAM. can I simulate this with dieselEngineFoam? If not, which solver I must use?
If I can use dieselEngineFoam, can I use (CH4) mass fraction in initial condition such as O2 and N2?
I want to calculate heat release rate (j/s), but in dieselEngineFoam output, dimension of dQ is (kg/(m^3*s)). How can I calculate heat release rate (j/s)? Do I have to change code?
Thanks.
