In concentrated solar energy applications, the Stirling engine is optimum option for extracting mechanical work. The engine's most notable features are minimal noise, vibration, and pollution, as well its capacity to function with any external heat source, including biomass, energy, industrial waste. gamma-type STE-1008 subject of our research. This can handle a maximum charging pressure 10 bar...

Pollution emission levels of aircraft engines are a nowadays high concern. Any technological advance that could reduce emission levels is always welcome. In what concerns aircraft engines, a possible solution for this problem could be the use of regenerators and intercoolers. These components might reduce the specific fuel consumption, increase efficiency and specific thrust and consequently re...

It is well known that small amount Piperazine (PZ) enhance the CO2 absorption properties of tertiary amine aqueous solution. Because the tert-amine has the lower heat of reaction, the blended amine solution, tert-amine with PZ, is attractive for low energy absorbent. There are some reports about the investigation of the mechanism of the blended amine solution, however, there still a difficulty ...

The Stirling cycle engine is gaining increasing attention in the current energy market as a clean, quiet and versatile prime mover for use in such situations as solar thermal generation, micro cogeneration and other micro distributed generation situations. A theoretical Stirling cycle engine model is developed. Using a theoretical decoupled engine configuration in which working space swept volu...

We propose and numerically investigate a phase regeneration technique that allows an M-PSK signal to be phase regenerated by an M/2-PSK (or even M/4-PSK) phase regenerator (applicable for M = 2, with k an integer). This scheme comprises three main parts; firstly, phase harmonic generation is used to create the second and third phase harmonics, secondly, the second phase harmonic (a down-convert...

Introduction. In this letter we report briefly the result of a measurement of the mass difference Am = mLms, where mL and ms are the masses of the long and short lived neutral kaons respectively. The experimental details will be presented more completely elsewhere. The method consists of the comparison of the intensity of the KS regenerated from a K, beam in two slabs of matter separated at dif...
