'Water flow analysis around 720 boat' simulation project by dheiny


#1

I created a new simulation project called 'Water flow analysis around 720 boat':

CAD model is done by @quequen, explained in this thread: https://www.simscale.com/forum/t/collaborative-simulation-project-multiphase-flow-around-a-boat-hull/71/54


More of my public projects can be found here.

Daid, a small leeway angle (as in https://www.simscale.com/projects/quequen/720-stepap203) will show more reliable outcomes from the appendages (keel and rudder).

@quequen - the link does not work, could you check?


#5

David, actually, the geometry that shows a more realistic situation is the one you called “4 degrees vertical”. The hull is horizontal and the leeway is right. Anyway I can’t see where exactly the water-plane is located (related to the hull), in order to check if displacement is close to a real situation. I think some orthogonal views (without perspective) would be helpfull.


#6

Sorry David, now that I look it well, “4 deg vertical” is wrong too: the boat is rotated 4 degrees over vertical axis, but in wrong direction. It should be rotated counterclock wise (seeing from top view).

@quequen - ah I see. I anyways wanted to try out a new CAD system to handle such free form shapes. Will get back soon.
