If you answered yes to any of these questions, then you are in the right place. In this article, I will explain what free and moving boundary problems are, how they can be solved using the Crank-Nicolson method, why this book is important, and how you can get it for free. I will also cover some of the types, methods, and applications of free and moving boundary problems in various fields. By the end of this article, you will have a better understanding of this fascinating subject and a valuable resource to learn more.


What are free and moving boundary problems?




Free and moving boundary problems are a class of partial differential equations (PDEs) that involve unknown boundaries that change over time or space. Unlike fixed boundary problems, where the boundaries are known and constant, free and moving boundary problems have boundaries that depend on the solution of the PDEs. This makes them more challenging and interesting to study.


Free and moving boundary problems arise in many physical phenomena where there is a change of phase, state, or shape of a material or a fluid. For example, when ice melts into water, when a bubble grows or shrinks in a liquid, when a tumor grows or shrinks in a tissue, or when a crack propagates in a solid. These are all examples of free and moving boundary problems.


What is the Crank-Nicolson method?




The Crank-Nicolson method is a numerical method for solving PDEs that was developed by John Crank and Phyllis Nicolson in 1947. It is based on the idea of using a finite difference scheme that is both implicit and explicit. This means that it uses both the values of the solution at the previous time step and at the current time step to calculate the values at the next time step. This makes it more accurate and stable than other methods that are only implicit or explicit.


The Crank-Nicolson method is especially useful for solving free and moving boundary problems because it can handle both parabolic and elliptic PDEs. Parabolic PDEs are those that describe heat diffusion or wave propagation, while elliptic PDEs are those that describe steady-state or equilibrium situations. Many free and moving boundary problems involve both types of PDEs, so the Crank-Nicolson method can handle them efficiently.


Why is this book important?




The book "Free And Moving Boundary Problems" by John Crank was published in 1984 by Oxford University Press. It is considered to be one of the most comprehensive and authoritative books on this topic. It covers both the theory and the practice of solving free and moving boundary problems using numerical methods, especially the Crank-Nicolson method. It also provides many examples and applications of free and moving boundary problems in various fields, such as metallurgy, geology, biology, and medicine.


The book is important because it provides a clear and rigorous exposition of the mathematical concepts and techniques involved in free and moving boundary problems. It also shows how these problems can be modeled and solved using computers. It is a valuable reference for researchers, students, and practitioners who are interested in this subject.


Types of Free And Moving Boundary Problems




There are many types of free and moving boundary problems, depending on the nature of the boundary, the PDEs involved, and the physical situation. Here are some of the most common types:


Stefan problems




Stefan problems are free and moving boundary problems that involve a change of phase or state of a material. For example, when a solid melts into a liquid, or when a liquid vaporizes into a gas. The boundary between the two phases is unknown and depends on the temperature and the heat flux. Stefan problems are named after Josef Stefan, who studied them in the 19th century.


Hele-Shaw problems




Hele-Shaw problems are free and moving boundary problems that involve the flow of a viscous fluid in a narrow gap between two plates. For example, when oil is injected into a porous medium, or when air is blown into a bubble. The boundary of the fluid is unknown and depends on the pressure and the velocity. Hele-Shaw problems are named after Henry Hele-Shaw, who studied them in the late 19th and early 20th century.


Phase-field problems




Phase-field problems are free and moving boundary problems that involve a smooth transition between two phases or states of a material. For example, when a solid undergoes a phase transformation, or when a liquid crystal changes its orientation. The boundary between the two phases is not sharp but diffuse, and depends on an order parameter that varies continuously. Phase-field problems are named after Lev Landau and Evgeny Lifshitz, who introduced the phase-field concept in the 1930s.


Numerical Methods for Solving Free And Moving Boundary Problems




There are many numerical methods for solving free and moving boundary problems, depending on the type of problem, the PDEs involved, and the desired accuracy and efficiency. Here are some of the most common methods:


Finite difference methods




Finite difference methods are numerical methods that approximate the PDEs by using discrete values of the solution at discrete points in space and time. For example, using the Crank-Nicolson method to solve the heat equation. Finite difference methods are easy to implement and understand, but they may suffer from stability issues or grid dependence.


Finite element methods




Finite element methods are numerical methods that approximate the PDEs by using basis functions that span a finite dimensional space. For example, using linear or quadratic functions to represent the solution over triangular or rectangular elements. Finite element methods are more flexible and accurate than finite difference methods, but they may require more computational resources or complex algorithms.


Boundary element methods




Boundary element methods are numerical methods that approximate the PDEs by using integral equations that involve only the values of the solution on the boundaries. For example, using Green's functions to represent the solution as a sum of sources or sinks on the boundaries. Boundary element methods are more efficient and elegant than finite difference or finite element methods, but they may require special treatment for singularities or nonlinearities.


Applications of Free And Moving Boundary Problems




Free and moving boundary problems have many applications in various fields of science and engineering, where they can model complex phenomena that involve changes of phase, state, or shape. Here are some examples:


Solidification and melting




Solidification and melting are processes where a material changes from solid to liquid or vice versa. For example, when metal is cast into a mold, when ice forms on a lake, or when chocolate melts in your mouth. These processes can be modeled by Stefan problems that involve heat transfer and phase change.


Fluid flow and filtration




Fluid flow and filtration are processes where a fluid moves through a porous medium or a narrow gap. For example, when water flows through soil, when oil is extracted from rocks, or when coffee is brewed in a filter. These processes can be modeled by Hele-Shaw problems that involve Darcy's law and fluid mechanics.


Biological and medical phenomena




```html that involve the growth or shrinkage of cells, tissues, or organs. For example, when a tumor develops or regresses, when a wound heals or reopens, or when a blood vessel expands or contracts. These processes can be modeled by phase-field problems that involve reaction-diffusion equations and biomechanics.
