A new regenerator matrix design that improves the efficiency of a Stirling engine has been developed in a numerical study of the existing SM5 Stirling engine. A new, detailed, one-dimensional Stirling engine model that delivers results in good agreement with experimental data was used for mapping the performance of the engine, for mapping the effects of regenerator matrix temperature oscillatio...

We propose and numerically analyse an asynchronous digital optical regenerator using a single-EAM loop and a novel neighbor-combine approach. It effectively re-synchronizes input signals with arbitrary phases to the local clock, and regenerates signals with high amplitude fluctuation and polarization mode dispersion. We demonstrate the application of this regenerator for 4x40 Gbit/s WDM to 160 ...

The focus of this work is the modeling and performance comparison of different models of pulse tube refrigerators, namely, the Orifice Pulse Tube Refrigerator (OPTR) and the Inertancetube Pulse Tube Refrigerator (IPTR) with both in-line as well as coaxial configurations. A detailed analysis of the flow and heat transfer in various components of the above mentioned models under oscillating flow ...

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...

As data communications rates climb toward 10 Gbits/s, clock recovery and synchronization become more difficult, if not impossible, using conventional electronic circuits. The high-speed photonic clock regenerator described in this article may be more suitable for such use. This photonic regenerator is based on a previously reported photonic oscillator capable of fast acquisition and synchroniza...

Thermoacoustic converters are devices for direct conversion of acoustic energy into thermal in the form temperature difference, or vice versa – converting an wave. In first case, device is called a thermoacoustic heat pump, second engine. can use (or produce) standing travelling This paper describes construction and properties single-stage engine with kind works using Stirling cycle. It uses ga...
