9781334226588: A Finite Difference Method for the Solution of Free Boundary Problems

Synopsis

This book outlines a new systematic iterative procedure for solving steady free boundary problems, which are common in plasma physics and fluid dynamics. Free boundary problems are difficult to solve because they involve a complex equation that describes the behaviour of a fluid, and an unknown boundary that is determined by the solution to the equation. The author's method involves introducing a fixed rectangle as the parameter domain, and seeking the solution as a conformal transformation from the rectangle to the physical plane. The book provides a detailed description of the method, including the derivation of the governing equations, the formulation of the equations for specific models, and the numerical implementation. The author also presents the results of computations for several models, including the vena contracta and Riabouchinsky models for both plane and axially symmetric geometries, and a simplified equilibrium model of plasma physics. The book concludes with a discussion of the accuracy and convergence of the method, and its potential for solving a variety of problems with two independent variables.
