boiler block 2

About this project

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.
