Can anyone help with this fluid sim?

I’m working on a house in the rain and just don’t know how to get water to realistically drip off of things. The particle system doesn’t “drip” as much just appears. I’ve tried fluid sim, but I can’t reduce the scale. I’ve attached a simple window blend that is like what I want water dripping off of. I set it up with a fluid sim that is just too large. Can anyone help?
