This paper uses second-order software for evaluating five Stirling engine parameter?s effect on its performance to select an appropriate configuration with optimal dimensions use in a concentrated solar power plant. Appropriate configuration, heater shape, bundle tube heat exchanger size, and regenerator type geometry are studied. Results show that Alpha is the most suitable high-temperature di...

We review the application of the Wigner-Weisskopf model to the two-channel decay problem for the neutral K meson system in the resolvent formalism. The residues in the pole approximation are not orthogonal, leading to additional interference terms in the K S − K L 2π channel. We show that these terms may be detectable experimentally in the beam emitted from a regenerator.

Aiming at improving the performance of Organic Rankine Cycle (ORC) system with low-grade steam as heat source, this work studied and optimized main operating parameters ORC system. The effects evaporation temperature, superheat degree, condensation temperature regenerator pinch difference on were obtained. optimization for is based indicators specific net power output, waste pollution, cycle ex...

We present the first experimental demonstration of an asynchronous digital optical regenerator at 42.67 Gbit/s. The system effectively retimes incoming asynchronous data bursts to a local clock without burst mode clock recovery and converts the signal to a desired wavelength and duty cycle. ©2008 Optical Society of America OCIS codes: (060.2330) Fiber optics communications; (060.4510) Optical c...

The paper presents the results of simulation tests hydraulic resistance and temperature distribution prototype Stirling alpha engine supplied with waste heat. following elements were analyzed: heater, regenerator cooler. uses compressed air as a working gas. Analyses carried out for three pressure values and different speeds. work was in order to optimize the configuration due minimization hydr...
