The Magneto Caloric Effect is an intrinsic property of a magnetic solid. It is the response of this solid to the application or removal of magnetic fields [1]. When magnetic material is subjected to a magnetic field the magnetic moments are aligned and the magnetic entropy is lower. And the sample heats up when the field is removed the magnetic entropy is increased and the temperature is lowere...

The design of heat transfer performance regenerator is the key technology Stirling machine and great significance to ensure operation efficiency equipment. In this study temperature difference between two ends at room less than 50K. This paper attempts straight channel grid verify its accuracy. At first, a straight-channel was designed in by analyzing influence structural parameters on order re...

The profitability impacts of solvent storage are modeled for new coal and natural gas-fired power plants with amine and ammonia-based post-combustion CCS facing variable electricity prices. With perfect information of future prices, up to 3 hours of solvent storage was valuable due to price volatility at carbon prices up to $40/tonne CO2 and no regenerator undersize. With imperfect information ...

Theoretical and experimental investigations indicate that at high loads such as 3/4 throttling or more speeds 3000 rpm more, the exhaust gas temperatures of Internal Combustion engines are about 900-1000 K. The amount heat wasted with is equivalent to power them. By considering this feature engines, a Hybrid engine consisting an (IC) gamma type Stirling was proposed analyzed from thermodynamic ...

Different traditional and advanced control strategies have been tested and the performance investigated, revealing their incentives. The investigated control approaches are: conventional decentralized PID control, MPC control based on analytical model, MPC based on Artificial Neural Networks (ANN) model and Fuzzy Logic Control (FLC). Comparative control results are shown for the multivariable c...

This paper presents the exergy analysis and optimization of the Stirling engine, which has enormous potential for use in the renewable energy industry as it is quiet, efficient, and can operate with a variety of different heat sources and, therefore, has multi-fuel capabilities. This work aims to present a method that can be used by a Stirling engine designer to quickly and efficiently find nea...

Energy and exergy analyses were performed on a glass furnace regenerator hydrogen production via thermal catalytic ammonia decomposition. A novel integration between energy was suggested to predict the performance of thermodynamic systems. It found that heat recovered by combustion air south side higher than north because fouling effect deposit materials lost through walls. The maximum efficien...
