Structural Study on Moving Magnet Compressor for Stirling Engine
The article describes a structural study on moving magnet compressor for Stirling engine. The performance of Stirling engine is determined by the linear compressor. The article first establishes mathematics models for ordinary linear compressors and moving magnet compressors manufactured for test and analysis, then studies magnetic field distribution of linear moving magnet compressor by CAE, the results show that magnet analysis has an agreement with the measurements. A modified moving magnet compressor prototype is proposed based on the results.
A study on the linear compressor characteristics of the Stirling cryocooler
Abstract The purpose of this study is to analyze the characteristics of the linear compressor for Stirling cryocooler. To ensure high performance and long life of the free piston, free displacer Stirling cryocooler, the operating parameters of the linear compressor should be optimized. The experimental results show the operating frequency of the linear compressor has significant effect to the input power characteristics, and the compressor with higher charging pressure of working fluid has high pressure ratio. For the high performance of the linear compressor, compressor has uniform magnetic force with different stroke, and the optimal operating frequency with respect to the charging pressure.
Phenomenology and homeopathy.
There is a great overlap between the way of seeing the world in clinical homeopathy and in the technical philosophical system known as phenomenology. A knowledge of phenomenologic principles reveals Hahnemann to have been an unwitting phenomenologist. The ideas of phenomenology as applied to medicine show that homeopathy is the ideal medical system to fulfill the goals of coming ever closer to true patient concerns and experience of illness.
