Hi,

I am working on simulation of flow past a cylinder when cylinder is under a forced oscillation. I have a question regarding this case and would like to know your opinions.


To simulate the cylinder oscillation, in order to preserve the mesh quality, I implement the motion to the entire flow domain. This means that the whole domain is oscillating with a velocity field resembles the original cylinder motion. Do you guys think I need to consider any extra terms when calculating the lift force? Currently, I am just integrating the pressure on the cylinder to calculate the lift, but I thought I might miss some other unseen forces due to simplifying the problem.

Thanks,
A E
