In the steam power plant, working medium used for energy transformation is water vapor. The thermodynamic properties of vapor are usually obtained by using tables and charts. Adiabatic process widespread in engineering applications. adiabatic realized without heat addition or rejection entropy during a reversible remains constant. During an expansion process, superheated turns into saturated , ...

We present a thermo-statistical model of popcorn production and propose a way to control the final size of the popcorn by monitoring only the chamber pressure. P.A.C.S: 05.20-y, 01.55.+b, 01.90+g, 05.70-2. How can one control the size of popcorn? The food industry may have ample reason to seek for ways to double or triple the size of popcorn, because large popcorn may be pleasing to the eyes, p...

We study the adiabatic density perturbation in the oscillating inflation, proposed by Damour and Mukhanov. The recent study of the cosmological perturbation during reheating shows that the adiabatic fluctuation behaves like as the perfect fluid and no significant amplification occurs on super-horizon scales. In the oscillating inflation, however, the accelerated expansion takes place during the...

in the present study the adiabatic temperature of gaseous fuels were calculated and the influence of effective parameters of flame temperature was discussed. firstly, a new computational program named ftc (flame temperature calculations) was prepared to calculate the adiabatic flame temperature and then the effect of initial temperatures of combustion air and fuel, excess air content and oxygen...

We show that recent results on adiabatic theory for interacting gapped many-body systems finite lattices remain valid in the thermodynamic limit. More precisely, we prove a generalized super-adiabatic theorem automorphism group describing infinite volume dynamics quasi-local algebra of observables. The key assumption is existence sequence Hamiltonians, which generates same Our also holds certai...

We localize Cs atoms in wavelength-sized potential wells of an optical lattice, and cool them to a three-dimensional temperature of 700 nK by adiabatic expansion. In the optical lattice we precool the atoms to ø1 mK. We then reduce the trapping potential in a few hundred ms, causing the atomic center-of-mass distribution to expand and the temperature to decrease by an amount which agrees with a...
