Converging Diverging Nozzle with dbnsTurbFoam

Saleh Abuhanieh · January 4, 2019, 01:30

Hi Foamers,

I used different solvers to estimate the location of the shock wave for the subject case, namely: rhoSimpleFoam, sonicFoam, and rhoCentralFoam using OpenFoam 5.0. However the estimations/results for these solvers were not so accurate comparing to the experimental results.

I am trying to solve the same case using dbnsTurboFoam (density based solver available only in foam-extend 4.0) with no success till now, the value of h is going high very rapidly and floating point exception occurs at the end.

You may find the complete case folder via the below link, you can see that I tried different BC and thermophysicalProperties.

Any kind of support will be appreciated.
Thank you in advance.

Well .. I know this solver is not so common.. but I am sure many Foamers did it..

Hi

Were you able to solve the issue? I am using the same solver and encounter similar problems.

Many thanks

Hi Thomas,

Unfortunately no.

I assume I have a similar issue...The geometry I am modeling is a stator blade with a fixed inlet velocity, fixed inlet temperature and a waveTransmissive outlet. Maybe someone has an idea where the issue could be found. The Mesh seems alright with a non-orthogonality of Max: 45.89 and an average: 16.36.
I first suspected the thermophysical properties but they seem alright to me:

PHP Code:


			
thermoType
hPsiThermo<pureMixture<constTransport<specieThermo<hConstThermo<perfectGas>>>>>;

// name, nMoles, mol weight, CP, Hf, mu, Pr;
mixture         air 1 28.9 1005 0 1.82e-05 0.71;

This is the output I get when I run it. This clearly indicates that something goes wrong as the velocity also shoots up to unrealistic numbers.

Maybe someone has an idea where the issue could be found. The Mesh seems alright with a non-orthogonality of Max: 45.89 and an average: 16.36. I first suspected the thermophysical properties but they seem alright to me: PHP Code: `thermoType hPsiThermo<pureMixture<constTransport<specieThermo<hConstThermo<perfectGas>>>>>; // name, nMoles, mol weight, CP, Hf, mu, Pr; mixture air 1 28.9 1005 0 1.82e-05 0.71;` This is the output I get when I run it. This clearly indicates that something goes wrong as the velocity also shoots up to unrealistic numbers.
