摘要
本文在有限差分方法的基础上,应用循环迭代方法,成功地求解了一组非线性抛物型偏微分方程。解决了托卡马克等离子体欧姆加热能量输运的数值计算问题,所获得的结果与理论分析一致。
A set of nonlinear second order parabolic partial differential equations with initial-boundary values is approxinated by Crank-Nicholson difference method, and successfully solved by means of Loop-Iteration method. The computation of energy transport in tokamak plasma by ohmic heating provides numerical results in agreement with the theoretial analysis.
