A new fluid-drive gas compressor using magnetic fluid and traveling magnetism is investigated. Its principle is as follows. Consider a cylinder equipped with a linear motor which generates successive magnetic fields traveling along the cylinder axis. At one end of the cylinder, magnetic fluid (MF) and gas flow alternately into it. Immediately after entering, the MF is formed into successive slugs by the magnetism of the linear motor, and each slug is drawn towards the other end. The gas between MF slugs can be thrust and thus compressed. In order to confirm the feasibility of this compressor, a simplified test was conducted by means of permanent magnets instead of the linear motor. The results of both this test and the comparison with the analytical model proposed here are presented and discussed.
