Mass Transfer Processes: Modeling, Computations, and Design

Chapter 8. Transient Diffusion Processes

Learning Objectives

After completing this chapter, you will be able to:

• Understand and use the separation of variables method for the solution of homogeneous linear partial differential equations.

• Use the modified method of separation of variables for non-homogeneous problems.

• Understand the superposition method for the solution of multidimensional transient diffusion problems.

• Solve transient problems posed on a semi-infinite domain.

• Understand the concepts behind the penetration model for mass transfer from a gas–liquid interface.

• Solve eigenvalue problems with the CHEBFUN program.

• Solve partial differential equations numerically with the PDEPE program in MATLAB.

In Chapter 2 we briefly examined ...
