Background

The current commonly used magnetic fluid power generation system generally adopts a compressed air and liquid mixing mode: the gas is compressed by the compressor to become high-pressure air, and the high-pressure air is mixed with the liquid metal in the mixer to push the liquid metal to flow. The principle of this pushing method is to use the pressure reduction of air in the mixer to make the air self-volume increase and expand. The mixing process does not involve the utilization of external heat energy, the kinetic energy obtained by the liquid metal is derived from the electric energy consumed by the compressor for compressing air, the kinetic energy of the liquid metal is converted into the electric energy through the power generation channel, and the energy conversion path of the magnetofluid power generation system is as follows: electric → kinetic → electric, considering the loss of energy utilization conversion, it can be speculated that the final output electric energy of the whole system will be less than the consumed electric energy, and it is not practical to generate electricity by using the hybrid scheme alone. Meanwhile, high-pressure gas enters the magnetic fluid and then generates a cavitation effect on the inner side of the pipe wall in the flowing process, so that cavitation erosion is caused to the pipeline, and meanwhile, the high-pressure gas occupies most space of the pipeline, so that power generation equipment manufactured by the method is low in power generation efficiency.
