Analysis of Blasius Flow for flat plates, corner flow, and delayed corner flow; of incompressible and compressible flow.

Update
Sim run1 was set up as Pressure inlet + Pressure outlet. I was told that this 'boundary condition combination is very poor in terms of stability'. I don't think the data is any good?
Sim run2 was set up as velocity inlet + pressure outlet. I was told this was better and should stop any diverging. 

Does it flow? 
It is a fluid heat transfer block/water boiler block. The block goes onto heat source, water gets pumped into it, and aim is to heat up the water.

To increase the surface area there are lots of fins inside, and fluid needs to turn 180, so the fins at the turn are in a radial pattern.

I wanted to simulate the water flow to see what it might do, and see if there are any massive dead spots.

Seems like there is a lot of interesting things going on.
