Discussion Overview

The discussion focuses on the analysis of turbomachines using Computational Fluid Dynamics (CFD) tools such as GAMBIT and Fluent. Participants explore the need for foundational knowledge in CFD principles, the importance of validation and interpretation of results, and seek guidance on obtaining experimental data and tutorials relevant to their research.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant expresses a desire to learn about turbomachines analysis in GAMBIT and Fluent for their master's thesis on the effect of stagger angle on turbine blade cascade.
  • Another participant emphasizes the necessity of understanding CFD principles to avoid misinterpretation of results, warning that inexperienced users can produce significantly inaccurate outcomes.
  • The original poster mentions having a background in CFD and seeks guidance on obtaining experimental data, tutorials, and research reports related to turbomachines.
  • A suggestion is made that experimental data is likely proprietary and that journal research or resources like the NASA Technical Reports server may be useful for finding data.

Areas of Agreement / Disagreement

Participants generally agree on the importance of foundational knowledge in CFD and the challenges associated with obtaining experimental data. However, there is no consensus on specific resources or methods for acquiring tutorials and data.

Contextual Notes

Participants express varying levels of experience with CFD, and there are unresolved questions regarding the best approaches to gather experimental data and tutorials for turbomachine analysis.

Who May Find This Useful

Students and researchers interested in CFD applications in turbomachines, particularly those working on related master's theses or projects.

hi,
I want to learn turbo machines analysis in GAMBIT and Fluent...
Anyone who have experience of CFD please help me...
please give me if u have any tutorials (apart from given within softwares)...
I am working for my masters thesis on effect of stagger angle on turbine blade cascade.
Thank you.

You really need to learn CFD principles in general. People who use CFD or even FEA for that matter can be dangerous; seriously. It is way to easy to throw a model into Fluent/CFX/etc, and get an answer. Without background, you'll have no idea how accurate that answer is.

An experienced and inexperienced CFD'er solving the exact same problem could be as far off as 50%. Find some tutorials, but if you're doing a masters, Sign up for Computational Fluid Dynamics!. Write a 1D solver. Then write a pseudo 2D solver. Then learn principles of meshing. Then start your thesis. You have plenty of time, don't rush it.
 
hi
Thanks for reply.
I know the fundamentals of CFD and I have also done a course on CFD in first year of M.Tech. degree.I am B.E.(Aeronautical) so I have CFD background.I have written some small programs on C for heat transfer and 2-D fluid flow but I don't want to go into coding side.
I agree with u on the thing that experience is required on Fluent and otherwise anyone can solve problem but interpretation plus validation is important.Therefore I need help of some person who can guide me on 1.how to get experimental data on turbo machines 2.how to get some good tutorials on the same and send any research report if he have and overall any suggestions for how to go about dissertation.
Thank you.
 
Most experimental data I would assume is proprietary first off. Aside from that, you'll probably have to go journal hunting. You can also try the NASA Technical Reports server.
 
thanks...
