The Nuclear Power Thread
A couple of questions. I was reading up a tiny bit on reactors and I was introduced to pool-type reactors and research reactors (often used to provide medical isotopes). Now, I read about some low temperature non boiling lwr that were built to provide process heat and even some papers on low...- t92

A different Brayton Cycle concept.
Has anyone ever built a subatmospheric brayton-cycle piston engine? or a sub-atmospheric open stirling cycle?- t92

Can a Split Cycle HCCI Engine with External Compression Work?
yes 2:1 - 4:1 compression, but coupled with 6:1 - 12:1 expansion. I think a little compression goes a long way in improving the thermodynamics. Particularly when you have a very large expansion piston, as in this design. I did do a spreadsheet based on the adiabatic relationship. Okay the...- t92

Can a Split Cycle HCCI Engine with External Compression Work?
the compression ratio will be quite low between 2 and 4 perhaps. So I don't think it will be hot enough to knock. Or am I missing something?- t92

Understanding Muonium Energy Levels and Relativistic Velocities
so does this mean the de broglie wavelength is 1/200th of that of an electron? and the velocity is approx 14 times higher than that of an electron - and if so are we anywhere near relativistic speeds yet? If two positive muons were bound to one negative muon in the same manner as a h2+ ion...- t92

Can a Split Cycle HCCI Engine with External Compression Work?
I was wondering about a split cycle engine too this week. In this version the piston compresses say 2/3 of the air into a separate reservoir, then a valve shuts and the piston continues to compress the remaining third of the air to 1/6 of the cylinder volume, i.e to half the remaining air's...- t92

Graduate Why Is Pure Neutron Matter Not Common Outside Extreme Conditions?
I've been thinking about this problem too. And I understand the 15 minute thing is a limiting factor. But I still have another question, relating to the neutrons generated in the sun. btw its been 14 years since I did my degree so forgive me if my question is a bit naive. If a neutron is...- t92
