As you could read in our last blog, PH Spaanteknik has helped us to produce a number of prototype coaxial swirlers. We have now received them and I just think you should see how nice they look.
They look really nice and the tolerances are much better than what we ourselves could do in our own workshop. Tomorrow we will start brazing the first elements together. As soon as the first elements are brazed together, we will perform a flow test with water. It is absolutely essential to know the characteristics with regard to flow of water as a function of inlet pressure. For that, we re-use part of the setup, which we previously used for water flow test of the BPM-5 injectors. However, it must be modified a bit so that these smaller injectors fit.
If you want to know a little more about how these coax swirlers work or just want to look at them a little more, then I have created a small video that describe the basics. It can be seen below:
