Traveling-wave thermoacoustic heat engines have been demonstrated to convert high-temperature heat to acoustic power with high efficiency without using moving parts. Electrodynamic linear alternators and compressors have demonstrated high acoustic-to-electric transduction efficiency as well as long maintenance-free lifetimes. By optimizing a small-scale traveling-wave thermoacoustic engine for use with an electrodynamic linear alternator, we have created a traveling-wave thermoacoustic electric generator; a power conversion system suitable for demanding applications such as electricity generation aboard spacecraft.

    Some foundational considerations on the peculiar status of the second law as a law of physics are made. Given the atomic nature of matter, whose behaviour is well described by statistical physics, the second law could not hold unconditionally, but only statistically. It is not an absolute law....

    The COBRA pulsed power generator has a variable current pulse wave form and amplitude (95–180 ns rise time, up to 1 MA peak current). It was designed to study wire array Z pinches and X pinches, including plasma formation, pinch implosion dynamics, and pinch plasma parameters as a...

    This note studies families of isothermal Navier-Stokes-Allen-Cahn systems that are parameterized by temperature. It shows that under natural assumptions, the possibility of traveling waves corresponding to phase boundaries arises during a phase transition at a critical temperature. Below that...
