I've been working a bit on the CFD-Wiki best practice guideline for turbomachinery CFD.

I'm a bit hesitant if the level I have chosen is good. Should the text be shorter or longer? Does it need to be more or less detailed? If you have any comments or suggestions about this please let me know. There are still many sections that are not written, but you should be able to get a feeling for the end-result by looking at the finished sections.

Dear Jona Larsson,

It is good effort. I would to suggest something:

The Methods to simulate turbomachinery flows are(Chima) :

succesive analysis method Averaging plane method average passage method sliding mesh

but in the text on CFD wiki it shows something else.

could you please define the relationship between two as i guess that is only differece of terms used for them by different authors.

my 2nd suggetion is to include the best practice guidlines for the heat transfer calcualtions as the mesh required for them should be in entropy sublayer (i.e 1% of thermla boundary layer) (make me correct if i am wrong). The main issue is that even 1.3 + million nodes are still not considerd mesh independet for single rotor passage.

Also what if any body only wants to compute the effeciney, pressure ratios , temprature drop or rise. what should be density and quality of grid.

What should be boundary conditions, where should be the inlet and outlet be placed.

And if possible can you any body provide the history of turbomachinery and relationship between development of gas turbine, steam turbine and water turbine. furthermore impact of advancement of one field on the other improvement.

thaks

Dear Jonas Larsson,

I also would like to suggest that you have done very quality work on turbomachinery.

Could you please provide something from your thesis and papers in simple way, which is both comprehensive to advanced users and also easy to understand to new user.

Thanks Regards SAM
