The geometry of a compressor leading edge has an important effect on the aerodynamic performance at off-designed incidence angle. current geometric design methods are usually developed based flow characteristics designed However, few research focuses quantitative rules angle in cascade. This situation restricts further optimization and development method. In this paper, starting from potential ...

Abstract This paper presents high-speed two wavelength interferometry for measuring fast phenomena, which allows to extend the dynamic range of measurement using different wavelengths at same time. The method was applied measure transonic airflow through a blade cascade

Shielded coherent synchrotron radiation is discussed for two cases: (1) a beam following a circular path midway between two parallel conducting plates, and (2) a b earn circulating in a toroidal chamber. Wake -fields and the energy radiated are computed for both cases. Under conditions like those of the high-energy bunch compressor of the Next Linear Collider (NLC), in which bunches as short as...

The efficiency of the valved linear compressor is very important to space J-T throttling refrigerator. To compare single-piston (SVLC) and symmetrical dual-piston (SDVLC), this paper explores factors that affect efficiency. Firstly, analyzes mechanical vibration system compressor, result shows highest when external force (current) in phase with speed. Then numerical solutions current velocity a...

In most modern manufacturing systems, products are often the output of some multistage processes. In these processes, the stages are dependent on each other, where the output quality of each stage depends also on the output quality of the previous stages. This property is called the cascade property. Although there are many studies in multistage process monitoring, there are fewer works on prof...
