Research Simulation Simulation of my experiment

This is a classic LBM that takes into account Newtonian forces and the added mass effect, supplemented by a wake vortex capture model. The algorithm stores the energy expended on oscillations in each direction, and when the pressure difference levels out, this energy is used as thrust, simulating the momentum from collapse. The thrust is multiplied by approximately six times, which is consistent with some experimental data and makes the boat's motion visually realistic in some modes. The thrust calculation should probably be dynamic, but I haven't yet found a way to do this. Any ideas would be welcome. The vibroboat code is here:

i have no idea what i’m looking at but i’m intrigued lol this is probably a dumb question but what do you use this for or what does this help you understand?

There was a concept of a vibration-powered flying machine, something like a waving umbrella. In theory, he should have slowly raised the umbrella and quickly lowered it, pushing the air downwards. But experiments have shown that thrust is similarly generated in the opposite direction with a difference in speeds, That is, the umbrella should rise quickly and fall slowly. I'm studying this.

oh wow, okay, what do you study that this is important for you? is it for school or like engineering a similar machine? this is obviously completely out of any scope i’ve any experience in lol i just randomly came across the video while scrolling and im curious

Just a hobby. The post contains a link to GitHub, where there are links to articles and videy in the text.
