Hello everyone,
I am an Aerospace Engineering student and I would like to work on a numerical simulation. As I wrote in the title, I would like to study the effects of wind on an industrial chimney. In particular, I already know how to model the vortex shedding problem in Ansys-Fluent. I would therefore like to know how to study the effect of these periodic forces on a chimney. Which program should I use? Which code should I use?
Thanks to those who will help me
If you are able to solve the flow problem around the chimney you have already in Fluent all the variables you need to compute the forces acting on the structure. Just integrate pressure and stresses along the walls.
It would not be a bad idea to take a look on fundamental science instead of targeting one algorithm to do it for you. Having said that, two parameters become essential here, one is the frequency and location of shedding - the other being the energy associated to critical vorticity.
As you mention... know how to model the vortex shedding problem in Ansys-Fluent. For a study of vortex shedding the important requirement is the frequency and the proportionality factor for vortex shedding is named Strouhal number.
I think setup a few points in the wake region for u-components and that should fluctuate with a certain frequency, Try to use FFT and mark your needed frequency from that.
