Fokker-Planck方程在快波加热中的应用

FOKKER PLANCK EQUATION IN THE APPLICATION OF FAST WAVE HEATING

快波加热算法，一般都是假定托卡马克中粒子为麦克斯韦分布．其实由于准线性扩散效应，共振粒子的平行温度与垂直温度不相等，这样必然产生一定的计算误差．针对这种情况，本文引入ＦｏｋｋｅｒＰｌａｎｃｋ方程。

Abstract The standard normal distribution for particles in tokamak geometry is usually assumed in fast wave heating.In fact,due to the quasi linear diffusion effect,the parallel and vertical temperatures of the resonant particles are not equal to each other,so,this will bring some error.For this case,the Fokker Planck equation is introduced in this paper,and iteration algorithm is adopted to solve the problem well.
