磁流体发电机的电流饱和现象研究

Research on Current Saturation Phenomenon of the Magnetohydrodynamic Generator

磁流体发电是一种高效,低污染的发电技术,同时也是一种较为复杂的技术。提出了以法拉第电场输出电功率的磁流体发电机中电流在一定磁场范围内会产生饱和现象,这就是影响其性能的一个新因素。解释了其产生的原因,提出了临界磁场理论,并推导了相应的临界磁场的普适方程式。饱和现象及临界磁场的提出,给研究磁流体发电机的工作人员在研究通道性能问题上提供了新的思路,尤其是在超导磁体在磁流体发电机上的应用问题上的研究。

Magnetohydrodynamic power generation is a high-effective,low-polluting and complicated generating electricity.The current in Magnetohydrodynamic generator will result in saturation phenomenon within a limited range of magnetic field by outputting electric power with Faraday electric field is introduced,which is a new factor that would effect its performance.Mainly explained the cause of this phenomenon,produced the theory of critical magnetic field,and deduced the pervasive equation of it.The propose of saturation phenomenon and critical magnetic field provide a new thought for researcher engaged in magnetohydrodynamic generator,especially those in superconductivity magnet application.
