Yes and no: it's being diverted, which implies *some* collision, but it's not "jet inpingement".
You also have an issue with the water entering the fin area: that's the equivalent of an orifice plate, and is restrictive.
Also, the first 90 is well over the core, and so is the second, but where does the third fall?
Don't give up: it's a good design. Maybe 3 * 120 degree turns would be interesting.
