This post opens with a plot of thrust from NewNozzle without a nozzle.... this is just from the heat pipe.
It should be noted that the heat pipe is 240 meters long, a meter or less wide, and very thin (less than a centimeter thick).

Re: Images for FluxBB: 32 second run of NewNozzle

This plot shows that there is an increase in thrust over the stretch from six seconds to 32.
The current theory about what is happening is a feedback loop, created by a setting for the intake.
According to this theory, OpenFOAM is automatically adjusting the force needed to push 2 kg/s into the heating tube.
This force contributes to the force recorded at the exit,
The solution under review is to record the force at the intake, and to subtract that force from the exit.
The result ** should ** match the Real Universe numbers we would see if this were a physical test article.

The plot below is wrong but at this point we don't know why.

The NewNozzle clase has NO nozzle.... Here is the corrected thrust plot
