1-way FSI Vs. 2-way FSI
 

Hello everyone

I'm on my bachelorthesis right now which deals with fluid-structure-interactions of helicopter blades.
A point of interest is whether a one-way FSI simulation or a two-way simulation is required or in other words: what would be the difference between those two approaches (thrust force and drag torque). As I couldnt successfully run a FSI simulation, I now need a paper that investigates that question. I am looking at micro helicopters in my work, which means a blade length of 5cm. However, papers with other systems would be appreciated as well.

Does anyone here know if such a paper exists? I couldnt find anything.. :(
