what is the problem?
is it related to injector model that i used?I used hollowconeinjector model as injector model.

please help me.

what is the problem?
is it related to injector model that i used?I used hollowconeinjector model as injector model.

please help me.

niklas June 3, 2009 02:46

did it work before you changed injector type?

what is the temperature of the gas and liquid ?

swirl injector
 
Hello Dear Dr;

before every things I am thankful for your replies dear.
yes it worked even when I changed injector type to commonrail injector and it still worked,but when I changed injector type to swirlinjector and just copy and paste swirlInjectorProps instead of commonRailInjectorProps in injectorProperties file,it generated this error.
I am confused.
is it related to injector model?should I change injector model to pressure swirl?

thanks
With Best Regard

pressure swirl injector model
 
It seems that I have to define three parameter for pressure swirl injector including:1-ConeAngle 2-ConeInterval 3-maxKv?do I have to define any more parameters?
what are these constant in the pressure swirl model:1-ConeInterval 2-maxKv?
Is there any reference or article that explain this model?

thanks
best regard

again...
check the source file if you are uncertain about things.
src/lagrangian/dieselSpray/spraySubModels/injectorModel/pressureSwirl/pressureSwirlInjector.C

coneAngle is the umbrellaAngle for the spray and coneInterval is the sprayAngle. I dont know if those terms are clearer or not.
but if you consult the source code the injected parcel will have the angle
calculated like this
Code:

    scalar c = rndGen_.scalar01();
    angle_ = coneAngle_[n]  + 2.0 * coneInterval_[n] * (0.5 - c) ;

maxKv is the injectors maximum allowed discharge coeffients,
which is used to calculate the velocity

Code:

  scalar v = kV * sqrt(2.0*deltaPressure/rhoFuel);

error is :

or in some case:

*** glibc detected *** dieselFoam: malloc(): memory corruption (fast): 0x0b5a3a70 ***


I changed several injector model but none of them worked.
it seems that dieselfoam has a bug.
could any body help me.
it is my injectorproperties file that I used:

please help me it is urgent.
thanks

error is :

or in some case:

*** glibc detected *** dieselFoam: malloc(): memory corruption (fast): 0x0b5a3a70 ***


I changed several injector model but none of them worked.
it seems that dieselfoam has a bug.
could any body help me?
I attach my injectorproperties file that I used.

please help me it is urgent.
thanks

any body know how can I fix it?

yup, there was a bug in the swirlInjector.

If you have different number of entries in the pressureProfile and massFlowRateProfile it wouldnt work.
I've attached a fix to solve this problem

save the unzipped file in src/lagrangian/dieselSpray/injector/swirlInjector/

then go to src/lagrangian/dieselSpray
and run 'wmake libso'

then you should be able to run dieselFoam

Hello Dear Dr ;

I am thank you for your kindly attention.

I did every things that you said but I faced error when I try to compile it with wmake libso command,I though that I have to change swirlInjector.h to fix this errors,I tried to do it but I can not completely fixed it.

I want you to please send me swirlInjector.h file,then I can fix it.

regard

niklas June 11, 2009 02:21

what on earth made you change the .h file??

I thought it was overwhelmingly obvious that you should save it as the .C file.

az1362f June 11, 2009 07:18

change .h file to include class
 
I did not change swirlInjector.c file to swirlInjector.h file.
after I copied swirlInjector.c to swirlInjector folder I tried to compiled it with wmake libso but it generated some errors like these :

I thought that these errors are generated because I did not redefine the swirlInjector.h file to include new members that you add in swirlInjector.c file like:

Foam::label Foam::swirlInjector::nHoles() const
{
return 1;
}

and it did not declare in swirlInjector.h then the compiler generated this error:

injector/swirlInjector/swirlInjector.C:240: error: no ‘Foam::label Foam::swirlIn jector::nHoles() const’ member function declared in class ‘Foam::swirlInjector’
injector/swirlInjector/swirlInjector.C

then because of this I tried to change the swirlInjector.h file to declare new function and data member, but it still generated errors(last attached file). I want you to send me a suggestion or swirlInjector.h file.

thanks
with regard

niklas June 11, 2009 07:24

ah, ok.

You are using 1.5.
please update to the latest git 1.5.x version.
the correction will already be there then.

liquid tip penetration
 
1 Attachment(s)
hi

I implemented these line in dieselfoam solver to save liquid peneteration lenght in every time step,but my result showed an approximately a constant liquid penetration.(for example 10.xxxx)

std :: fstream penet
penet.open("penetration.txt",std::ios::app);
penet << dieselSpray.liquidPenetration(1.0)<<"\t"<<runTime. timeName()<<"\n"<<endl;
penet.close();

what is my mistake?
I used default setting of dieselfoam tutorials.
I attached a penetration result.
please help me.

liquid & gas properties
 
hi

I solved my last problem.
I want to use a diesel fuel with density of 840 kg/m3 and nitrogen (N2) as a chamber gas.
how can I set this two parameters?
I checked C7H16 files (.C & .H) but I don't know some parameters,for example rho_(61.38396836, 0.26211, 540.2, 0.28141),I checked html document but it does not describe these parameters:

NSRDSfunc5 (scalar a, scalar b, scalar c, scalar d)

any body can describe them and say how can I get the description of another input parameters like
pv_(87.829, -6996.4, -9.8802, 7.2099e-06, 2),
hl_(540.20, 499121.791545248, 0.38795, 0, 0, 0),
cp_(540.20, 6.11976102401216, 3137.69909384855, 182.274175063868, -254.530511150515),etc.

can I set chamber gas by changing N2 and O2 files in 0 directory in dieselfoam tutorial directory?
how can I describe a chamber gas with a defined properties like density viscosity,etc?

please help me

az1362f June 15, 2009 17:13

gas and liquid property
 
hi

I solve my last problem but still I don't know how can I describe chamber gas?

for example for a chamber full of N2 as gas instead of air.

farbfilm June 16, 2009 03:21

Hi,

did you check the 'thermophsicalProperties'?? There you can specify an inert gas!
I think, in the '0'-directory you can then define the composition of your gas (with the 'N2' or 'O2'-files etc.)!
