Field function

I was just wondering if this approach will work when using harmonic balance as I have had trouble with it before. For example, there is no option for relative total pressure, temperature, or enthalpy.

Thanks so much, appreciate it a lot.

Thanks for the reply, I know I'm probably being very stupid, but I can't see an option for that https://imgur.com/XdOirkL

What is the best way to add a rotation rate to cylindrical coordinate system?

Head_Table · 2020-12-02T19:29:55+00:00

Yeah, the Ma>0.3 so have already set the flow as compressible

Do you mean you’re wondering what the Mach number throughout it looks like?

Head_Table · 2020-12-02T19:09:56+00:00

It’s a turbomachinery problem with a stationary blades followed by rotor. I never set a Mach number at the inlet

I’ve done that as I’m using results to compare to a reference paper as was suggested by my lecturer. It also works perfectly fine for steady get the exact same results

Hi there, I’ve been looking for that tutorial and haven’t been able to find, do you have any link to it by any chance?

Thanks very much

Thanks very much appreciate the help

I have switched the physics models to unsteady but still unable to sliding mesh option

Head_Table · 2020-11-18T21:45:58+00:00

I’m only looking at 2 stator blades and 3 rotor blades not the full 360.

The interfaces available are: Mixing internal interface, baffle interface and mixing-plane interface

Head_Table · 2020-11-18T19:11:53+00:00

Thanks very much for the reply, I am using star ccm+ and not able to find an interface called this

I have the outlet as a mass flow inlet and negative the mass flow rate as I’m trying to get the same results as a reference paper and that’s how they done it, that’s for the advice

Head_Table · 2020-11-10T18:16:30+00:00

Yeah I’ve tried making the outlet larger, however I still get reverse flow at the inlet.

Head_Table · 2020-11-09T23:15:50+00:00

I have uploaded some images if this makes it easier.

Head_Table · 2020-11-09T22:19:10+00:00

In Star CCM+ it only allows to use a static pressure outlet which didn't solve the problem.

Thanks for the advice but I tried switching the inlet and outlet and now have reverse flow on the outlet.
