I am interested in making a very small scraper blade that moves back and forth along a submerged surface, however I need to make it as hydrodynamic as possible so I disturb the liquid as little as possible.

I understand I can model different things such as wings in ANSYS, however most of the tutorials only focus on those that have one direction of travel. I need to design the most efficient shape that will be moved in both directions in a liquid.

I know there are a lot of variables to deal with, but I need some sort of starting point on how to approach the problem. Can anyone offer any suggestions?

Edit: included a picture to explain a bit better.

You would have to have a raised edge to catch the excess material which will cause some turbulence, the amount of material would dictate the height of the raised edge. Unless there is a material that will naturally attract the media being used, really don't see a way around it. I would try a blade with either side angled upwards towards the middle with a flat bottom and a channel on the top side in the middle that is just above the liquid to prevent turbulence on the trailing end that leads to a runoff area to the sides of the tank. The rate of travel will dictate angle as much as the depth and width of the channel. It can also be cammed in the middle so the trailing edge either way will raise some. Or looking from the top of the rectangle blade the raised portion could be a diamond in shape leading to the runoff area, more turbulence but easier to make.
