From addiator, "To illustrate what I am talking about, let me share a torque, power and RPM characteristic evaluated from theoretical analysis with all losses considered. This is is evaluated on a 1.2 kW uniflow engine, but the overall trend is valid for any steam engine. Nind is indicated power, M is torque. The different colored lines stand for cutoffs from 10 to 50%."
That engine you evaluated looks very similar to the 2 horsepower uniflow that I used for my domestic Heat-Power module. I would very much appreciate getting more data from your evaluation. Is there a report or technical paper? If so please e-mail me, thanks in advance.
