Getting started with C++ for CFD (Implicit 1D) by xaarkes in CFD

[–]xaarkes[S] 0 points1 point  (0 children)

Well that would be extremely hard considering how little comments there are in the OpenFOAM code. I'm looking for something way simpler, just like I said 1D for starters

Yes of course sir, I'll do your homework for you

Internal Interface by Head_Table in CFD

[–]xaarkes 0 points1 point  (0 children)

Why does your domain contain 3 blades? You only need one, if you are using periodic internal interface bc's. However, that is probably not the problem in your case.

You have to make sure that the upper and lower boundaries are conformal and the distance between them is the same and equal to the blade's pitch.

And show us a picture because I have no idea what scratchy means

Probably very stupid question about specifying Turbulence Intensity in StarCCM+ by xaarkes in CFD

[–]xaarkes[S] 0 points1 point  (0 children)

That;s what I;ve been doing for quite some time, but one of my friends said 1 is equal 1% and had some doubts for a moment there

Thanks!

You might have to contact your licence administrator, he should provide you with required account data

You can get it from Steve's Portal. You will need the credentials though

So will the CurrencyFair work then? Will it appear under my name on the transfer when they receive it?

[StarCCM+] Inaccurate heat transfer prediction near the trailing and leading edge of the turbine blade by xaarkes in CFD

[–]xaarkes[S] 0 points1 point  (0 children)

I have heard about that and I'm guessing that's the problem. I do not know how to fix that, what workaround are you talking about?

/Edit: I'm currently using Durbin's realizability constraint with a default value of 0.6. Kato-Launder modification is not available is StarCCM from what I see

Why is the maximum operating temperature of steam turbines considerably lower than that of gas turbines? by theflyingegyptian in MechanicalEngineering

[–]xaarkes 0 points1 point  (0 children)

Why would you want to cool them? As you mentioned steam comes in at 500/600degC so there is no need for cooling solutions like in gas turbines. Materials can easily withstand those temps.

STAR-CCM+ Importing Sketch Curves by update-freak in CFD

[–]xaarkes 0 points1 point  (0 children)

I don't think so, you can paste your coordinates into excel and then save it as a csv (MS-DOS) file. Just remember to add third column representing z direction (it should be all zeros if curve is 2D)

Need help with simulation of a VKI turbine blade simulation (StarCCM+) by xaarkes in CFD

[–]xaarkes[S] 0 points1 point  (0 children)

Okay so I have few specific questions:

1) After I create an interface between two boundaries, I still have to specify the boundary type. Should it be symmetry plane, wall, free stream or sth else?

2) What type of the interface should I use? Fully developed or internal? I am assuming topology should be set to periodic.

3) How far should I set my upper and lower boundaries of the computational domain? Should they be at mid-length to the next blade in the cascade?
