  • question about the mini-project

    Posted by Xin on March 15, 2024 at 1:50 pm

    Hi support team,

    I select the third problem, and I simulate the as required with Re number 220 and 500. As guideline states, the report can include as follows, I don’t know what I should include for this case, since the limitation is 12 to 20 pages. My thought is that analysing different Re and different algorithm for dynamic mesh. My question is that is this enough for 12 pages or it’s too much. Because the requirment states that the before doing the project I can discuss.

    Thank you.

    Hi,

    Dr. Kadapa is currently on a business trip, but rest assured, he will respond to your message. Please anticipate a slight delay in his reply. Your patience during this time is greatly appreciated.

    Regards,

    Hi Xin,

    You can present some background of the problem, a brief overview of the literature, problem setup, methodology and results (graphs, contours, energy output etc.) accompanied by discussion. This will be like a short paper but is flexible in format.

    The page count can be between 12 and 20. But don’t worry if you exceed this number. This is just an exercise for you to demonstrate what you learned in the course.

      Hi Dr Kadapa,

      I’m doing mini-project three, simulating transverse galloping, and I got results as follows. It seems that the natural frequency(displacemant frequecny) is close to vortex shedding frequency( frequency of lift force). I am not sure if it is this correct because galloping frequency is far away from vortex shedding frequency. And also the displacement is very small. Please can you explain where I am wrong?

      Thank in advance

      Best Regards,

      Xin Xiong

    Hi Xin,

    You may get into a lock-in zone depending on the parameters, and when it is outside the lock-in zone, the frequency of the response will still be at that of the lift force but with a smaller amplitude.

    What are the parameters you are using?

      Hi Dr kadap,

      I’m using the parameter as follows as required in the intruction.

    I don’t know the other parameters, like inlet velocity.

    Check this paper and try to use the same parameters for the rectangular you are using so you can compare your results.
