Being that my day job is a Computational Fluid Dynamics Engineer, it only made sense for me to do a simulation of my rocket. It is a 3D density based simulation with heat transfer through the walls conducted on a 1.2 million node grid on a 96 core, 768 GB ram simulation server.
In the inside of the thrust chamber the temperature is 5200 F and the coolant water is 70 degrees when it enters. You can see that the most important area is the throat of the rocket. I adjusted the range in the 3d image to be red at the temperature of boiling water. You can see that the coolant does not reach this temperature so we are in good shape there.
The next is a cross section of the aluminum in the throat. Here the melting temperature of aluminum is ~1200 F with a loss of most major material properties near 800 F. The coolant keeps the material in the throat region at a balmy 600 F which is perfect for the performance of the rocket.
