Pressure distribution on a wall

Hello Everyone,

I'd like to display the pressure distribution along a wall. How can i do this? I want to make a chart and not a contour plot, the x axis would be the angle from 0 to 360 degrees and the y axis the pressure.

Thank you guys in advance

Pressure distribution on a wall - just plot pressure on the wall object.

You want to make a chart? If x is rotation angle - angle from what? Averaged or sampled how?

My objective is to get pressure distribution over the wall. geometry is not axisymmetric. using k-epsilon with scalable wall function. system is at high pressure and temperature and i'm using average flow properties for a range. just before where it's crashing, i stopped the run and got this:

Looking at v-mom imbalance and specifically monitoring the boundary flow variables at blockage, i couldn't understand that why i'm getting this issue at this position. i've posted yplus contours and mesh of that region.

Kindly have a look at it please. I'll be thankful for your help.

regards,
AJ

yes, it's fluid domain. inlet from pipe sides. and outlet at bottom of the larger cylinder.

Describing here my approach (which I’ve conceived by going through a lot of topics in this forum).
I'm using k-epsilon model. I’m not intended to use k-omega because it needs so finer mesh near wall which lead to very high cell count and I’ve maximum 16 GB memory at the moment. So looking at Re~1.38e8, apparently very thin boundary layer, keeping memory limit in view, I decided to go for scalable wall function first.
----------------------------
y+ & first cell height (m)
11 & 2.9e-6
----------------------------
for this first cell height, i got very low orthogonal quality of mesh. FLUENT didn't accept it and i switched to standard wall function with this intention that i should get first my simulation going on with broad range setup having convergence. i can narrow down the y+ later.
Now for standard wall function y+ range i got:
----------------------------
y+ & first cell height (m)
30 & 8e-6
300 & 7.98e-5
----------------------------
i've been using FLUENT that's why i tried to make things work first in FLUENT. using 7.98e-5 m spacing, at connection of inlet pipes to larger cylindrical domain (at curvature) i got velocities higher than average inlet velocity (as expected). here, y+ was much more greater than 300. so i kept decreasing first cell height.

Now, i've reached from 7.98e-5 m to 1.1e-5 m. This is where i'm unable to simulate my problem in FLUENT further. Because orthogonal quality goes lower than 0.01 for mesh with first cell spacing lower than 1.1e-5 m because of this issue, it's not acceptable in FLUENT. Other parameters like min angle, skewness, determinant criterion were in acceptable ranges (which I learnt through this forum). So I tried to check this domain in CFX.

The only reason I’ve mentioned my approach is, i need guidance and things to be pointed out if I’m doing anything wrong in the method I’m going through. I understand it’s not a single-sitting-one-attempt-problem-solving job. After getting back to my PC, I’ll surely post figures related to my concerns described above.

looking at results, mass flow rate at outlet seems quite right. imbalances are low enough. pressure distribution seems as it was supposed to be. did you check y+ sir? :)
any advice(s) about what was there wrong? :confused: please.

P.S. btw i've learnt today a better way to arrange monitors in a windows. TY ^_^
I assume that you've geometry and blocking file from meshing thread. :)

It's really helpful. to be honest, i never read it before.

:cool:
will you share please about what did:
what y+ you achieved? did you change the meshing params? or whatever you think is worth sharing. :D

It's a steady state case. i need to move to transient simulation onwards for almost similar case but with a little modification with extra pipes added. that's why i'm concerned about it sir.

EDIT: I'm sorry. I didn't know that CATCH was a link itself. :)
got it.

I'll look into it. and will update soon.

There's a link in my prev. post. Download and see.

1. I used your geo and blocking. Just genereted mesh.
2. I changed solver settings. First I used Upwind advection scheme with auto timescale, then switched to High Res and used prev. results as initial guess. Though I didn't try to use High Res at first. Why did you try to use Specified Blend Factor and Local Timescale Factor? Defaults suit at most cases. Always try to advance from the simple to the complex.
3. I changed Total Energy HT model to Thermal Energy. I didn't investigate its influence on convergence, but are you sure that you need Total Energy? Do kinetic energy effects considerable in your case?

2. I'll take that advice.
I was not sure, just read somewhere that blend factor helps in convergence in CFX. Can you explain a little in what conditions a blend factor and local timescale factor to be used? it may be make it more clear to me to cross check my case.
3. I've not involved heating zone in this domain yet. (partially following your advice @ 2) But considering it, i chose total energy.
