what fuel injector do you use?
You mentioned a thrust augmenter and water injection, both of which would increase the mass flow rate, hence the thrust. In the application I’m considering (which is simply to generate a high latent heat of vaporization updraft for a work of art I’m putting together) it would be useful to get a rough estimate of what this ultimate mass flow rate would be, its average velocity and its average temperature.
I understand from reading your comments that the water volume flow rate is 3gal/min.
PS: Water injection can maximize combustion efficiency, leaving fewer high energy species in the exhaust and that should be measurable as increased thrust as well as the conversion of exhaust velocity into mass flow.
