Mathematical models and results of calculation of plasma equilibrium in a circular cylinder with three helical or straight imbedded current-carrying conductors (i.e., in a straightened analog of a toroidal Galathea trap) are presented. The equilibrium is described in the framework of two-dimensional boundary value problems with plane and helical analogs of the Grad-Shafranov equation for the scalar magnetic flux function. Problems with first-kind boundary conditions corresponding to a magnetically transparent boundary of the cylinder and problems with second-kind boundary conditions and a given value of the electric current flowing in plasma (in addition to those flowing in the conductors) are considered. Deformations of magnetoplasma configurations in the cylinder for different formulations of the above-specified problems are investigated numerically. 相似文献

Summary A simple method of solution is highlighted for solving a class of bioreaction-diffusion problems. By virtue of the proposed transformation the original boundary value problem is rendered into an equivalent initial value problem. Results are comparable to conventional methods, and have lower computational time requirements.NCL Communication. No. 5179 相似文献
